### <span style="text-decoration: underline;">**L5 Connector anti-theft chain link:**</span>

<table border="1" id="bkmrk-the-goal-of-this-des" style="border-collapse: collapse; width: 100%;"><colgroup><col style="width: 50.0596%;"></col><col style="width: 50.0596%;"></col></colgroup><tbody><tr><td>The goal of this design is to create a quick and simple way to lock or anchor power adapters to spiderboxes or similar distribution. I wanted to discourage/stop the average participant from stealing your adapter without creating a super permanent connection. The 1/16th cable is easily cut with dikes if someone abandons their adapter or is unable to unlock it. Someone with the right tools can quickly cut the cable. #### <span style="text-decoration: underline;">**Materials Used:**</span>

1x 28" 1/16th Steel Wire Rope \[$0.31 a foot, so about $0.70\]

2x 1/16th Aluminum Ferrules \[$1.15 per pair if buying 10 pack\]

1x L5-20P Adapter, $-15R \[$16-20\]

2x (optional) Brady 1.5x1" Self-Laminated Vinyl Wrap Label

2x (optional) 1.5-2" of 3/8th heat shrink

#### <span style="text-decoration: underline;">**Tools Needed:**</span>

1x Pair of Electrical Dikes (I used Linesmen Pliers, Klein Tools D213-9NE)

### <span style="text-decoration: underline;">**How to Build:**</span>

<p class="callout info">Reading about this while at UnScruz or the Burn? Find DennisR/Overseer, I carry little kits with all the necessary components.</p>

##### <span style="text-decoration: underline;">Step One:</span> Gather Materials

Everything listed here is available at Home Depot for affordable prices. This is about a $20 project, including the adapter but without tools. $2.50 without. If you're just making one or two, I would avoid buying the Tools; Home Depot staff can cut the 28" steel wire for you from their "purchase per foot" spool. One of your friends will have a pair of wire strippers with a wire crimp in its handle, or check out your local library if they have a tool rental program. Oakland Library's loan tools; these tools are most likely in their inventory. Borrowing them saves you $70.

#####   
<span style="text-decoration: underline;">Step Two:</span> Secure the Adapter to the cable

<p class="callout warning">Important: Do not pull the wire rope tight around the L5 adapter, as it will slowly chew away at the plastic cable shielding if it can't rotate. Leave enough extra wire in the loop for it to move freely around the L5 Adapter. </p>

Slide the Ferrule down the wire and create a loop around the L5 Adapter, leaving about 3/4" excess through the Ferrule. Because the loop's radius is so small/tight, you will need to hold the wires/furrule in place to crimp it. Using my non-dominant hand, I pinch both wires

<table border="1" id="bkmrk-slide-the-wires-thro" style="border-collapse: collapse; width: 100%; height: 173.797px;"><colgroup><col style="width: 27.2917%;"></col><col style="width: 40.2888%;"></col><col style="width: 32.4195%;"></col></colgroup><tbody><tr style="height: 173.797px;"><td style="height: 173.797px;">Slide the Wires through the Ferrule and around the Adapter, being tight enough that it can't slide through, but loose enough that the adapter can move freely.  
  
&lt;IMAGE&gt;</td><td style="height: 173.797px;">Using my non-dominant hand, I pinch both wires below the Ferrule to hold it in place.

&lt;IMAGE&gt;

</td><td style="height: 173.797px;">Using your Crimp tool, crimp 1/4th of the Ferrule on the edge. Once the first crimp is done you can let go of pinching the end and move the ferrule around as needed for effective crimping  
  
&lt;IMAGE&gt;</td></tr></tbody></table>

<p class="callout info">Note: If you're adding Heat Shrink \[Step Four\], add it to the cable now, don't heat it down till the end but add it before you create the second loop.</p>

##### <span style="text-decoration: underline;">Step Three:</span> Create the Locking Loop

Slide the Ferrule down the other side of the wire and create a loop just slightly bigger than the large end of the L5 Adapter, leaving about 3/4" excess through the Ferrule. Crimp the cable, and you're done!

<table border="1" id="bkmrk-slide-the-wires-thro-1" style="border-collapse: collapse; width: 100%; height: 173.797px;"><colgroup><col style="width: 27.2917%;"></col><col style="width: 40.2888%;"></col><col style="width: 32.4195%;"></col></colgroup><tbody><tr style="height: 173.797px;"><td style="height: 173.797px;">Slide the Wires through the Ferrule and around the Adapter, being tight enough that they can't slide through, but loose enough that the adapter can move freely.

##### <span style="text-decoration: underline;">Step Four:</span> Optional Features:

<span style="text-decoration: underline;">Add a Label with your contact info</span>: I use 1.5x1" Self Laminating labels used for CatX cables. They have a small label, .75"x1", with a long clear laminating half of the sticker design to wrap around a smaller cable once or twice. I double them up, adding two labels so my contact info is on both sides. Keep it simple, I recommend just your First name, last initial, and your phone number. Mine says "DENNISR" with my number under the name, or "PLEASE RETURN" with my number under it.

<table border="1" id="bkmrk-connect-the-two-labe" style="border-collapse: collapse; width: 100%; height: 173.797px;"><colgroup><col style="width: 27.1754%;"></col><col style="width: 40.4051%;"></col><col style="width: 32.4195%;"></col></colgroup><tbody><tr style="height: 173.797px;"><td style="height: 173.797px;">Connect the two Labels together.

</td><td style="height: 173.797px;">Please place the label side (top) down first on the adapter.

</td><td style="height: 173.797px;">Wrap it around the cable, letting the extra clear vinyl wrap over the label.

</td></tr></tbody></table>

<span style="text-decoration: underline;">Add heatshrink over the crimps:</span> Over time, the tail ends sticking out of the crimped surface will fray. It's recommended to treat the ends, but since the 1/16th cable is so small, there aren't many options. Most of the time, I see a thick, most likely two-layer, heatshrink over the Ferrule and the extra tail of wire. If you have advice on this one, please let me know. I've also seen people add solder to the ends to prevent fraying and extend longevity.

As I don't currently have a generator anymore, I thought I'd do my Spiderboxes. Having created the them camp Vault 21+ on Playa, it just made sense to keep the Fallout theme running.   
#### <span style="text-decoration: underline;">**Materials Used:**</span>

1x Vinyl Wrap, printed by my favorite shop, 11.5 x 22"

1x Various Heavy Duty cleaners and degreasers

#### <span style="text-decoration: underline;">**Tools Needed:**</span>

Heat Gun - Bauer \[Harbor Freight\] carries one for $35. If you buy a $150 Milwuakee one, you'll waste $115... It's a heat gun. (Say's the guy with his $215 cordless Makita Heat gun)

### <span style="text-decoration: underline;">**How to Build:**</span>

##### <span style="text-decoration: underline;">Step One:</span> Gather Materials

Don't use my design; be creative and create something unique to you! Create your own sticker with notes and warnings. I've always wanted to create a complete technical drawing of the electrical layout in the spider box for the cover plate.   
  
The drawing was done in Adobe Illustrator with an art board of 11.5 x 22". The actual drawing has curved corners that I really liked, but to keep the cost down, \[about $15-20 a print!\]. it didn't go through a plotter, so all the cutting is on me to do at home.

[![image.png](https://docs.retallickengineering.com/uploads/images/gallery/2026-04/scaled-1680-/OuPimage.png)](https://docs.retallickengineering.com/uploads/images/gallery/2026-04/OuPimage.png)  
  
I also made a pretend nameplate sticker as a part of the overall sticker. It might make more sense to make these as an alternative   
sticker that you just add. I was being a little lazy and just added them to the main drawing instead of two pieces.  
  
I like looking through Sci-Fi games or movies \[Especially 1970/1980s films: Alien / 5th Element\] like Avatar, Halo, Thunderbirds Are Go, Fallout, Starfield, and my friend Craig's Backyard for inspiration.

#####   
<span style="text-decoration: underline;">Step Two:</span> Send the drawing off to a print shop.

I highly recommend Silicon Valley Graphics. They have done most of my sticker printing since 2017. LoAnn and Usman are wonderful, quick to respond, and have a super quick turnaround time. Almost all of my orders have been processed the same day! Don't go to the big internet printers, go to your local and neighboring shop!   
  
I always let them know when prints are for events like UnScruz or Burning Man, and they tend to give me a good price in exchange for agreeing to do some of the cutting myself or using scrap material. Happy to have been a customer of theirs for almost a decade.

##### <span style="text-decoration: underline;">Step Three:</span> Attaching the Vinyl. 

<span style="color: rgb(68, 68, 68);">This was really hard and required a lot of patience. The photos referenced in this document are my first attempt ever, and if you look closely, you can see the sticker covered in little dots. Those are air bubbles trapped under the vinyl. Hopefully, by the time you're reading this, I've replaced it with another attempt! Usman, with SVG, informed me that the bubbles are most likely from an uneven surface. While I did a deep clean of the surface before, I still rushed the process a little bit. It will take some experimenting to get it just right. </span>
