Question: what are the exact dimensions of the unit out of box??? I read it was 10.5" in length, I assume that's in the package/box?
Document: over priced if you know how to connect this, you might as well go to homedepot buy a 1 gang box, outlet and used a old extension cord. would only cost less then 5.00.  also the unit is too big, they could easily made it alot smaller.
The rest of the install is very straight forward.The reason I didn't give the kit a 5 star rating is due to two different reasons:1) The box is pretty thick and could be made slimmer for a lower profile inside the safe when mounted.2) The cord is pretty short. It would have been nice to have a longer power cord in the event that your safe wasn't located right next to an outlet.Other than that the kit is great!
This product does everything it says it does. Don't get me wrong. There is no false advertising...but...when I got the product and looked in the package, I realized I could have done everything this product does for about $15 from a local hardware store.
There are other ways to add an outlet, but I liked the fact that everything came included in the package-including grommets to keep rraction on the cord from affecting the connections.It's a well built, relatively compact enclosure that worked nicely in my Canon safe.
Also, once you attach the grommets to the cord, they are REALLY hard to get apart. You have to be really careful not to break them. Overall, it took about 5 hours and 6 stores to find a drill bit, and 45 minutes to install the outlet. I just stuck mine to the carpet in the safe with the provided velcro. Works fine.
The kit has everything that you need to install the product except the tools. The only thing to be aware of is that you have to drill a 5/8's hole in your safe to put the cord and grommets through. I had a hard time finding a drill bit for a 3/8 drill to do it (unless you want to spend $40 on a unibit), so keep that in mind if you don't have have a 1/2 drill or the proper bit laying around.
This connector provides all the power I need in my gun safe. One outlet for safe lighting and one outlet for dehumidifier. I used the included velcro pads to install the box where ever it fit best in the safe. The large feedthrough gromet required me to drill sund a large hole in my gun safe will that I just left it off.
I ordered this kit to get electrical power in my Stack-On Total Defense gun safe. It comes with an inside grommet that maintains the integrity of the safe's fire insulating properties and a 90 degree grommet where it exits the vent hole you used in the back of the safe. This helps with cord placement when you put the safe next to the wall. The box can be either velcroed to the interior, or there are holes allowing screws to secure it to the interior.
Kit comes with everything you need.Its box is is way larger than it needs to be so it uses up more room in your safe. If I were to do over again I think I would have gone to Value Home and got the stuff there plus I know it would have been way cheaper to piece it together than buy a kit.But Oh well,live and learn. Its still a good product and is well made,if you dont know anything about wiring then this is the way to go.
Unit arrived with a clearance tag for $3 on it... which is probably what this kit is really worth. You'd probably be better off buying a plug and just using a regular power strip or extension cord. The plastic clips also didn't work for me - they wouldn't close over the thick cable. However the kit works fine and does what you want it to - put a plug anywhere you want.
Answer: yes
