I used this kit to create my own custom gun case from a steel locking tool cabinet (72"Hx36"Wx24"D). It works very well. I riveted the plates to the back of the cabinet to hold them in place and for a cleaner look. I was also able to add two 6-slot shelves above, two magazine shelves behind, and two single pistol pegs within the long guns.

Really do like this entire setup and it completely transformed the interior of my safe. It will cut down on the amount of guns you might have had in there before, at least it did for me. But my safe is much more organized and easier to get to the guns I will shoot more often. Let’s be honest, most safes say they can hold x and x amounts of guns but only if they’re crammed in there. You’re gonna spend some money but I believe it’s worth it. The skies the limit on what you can do. Pretty easy install but I suggest going to Lowes or Home Depot to get better sheetrock anchors. The ones they send are really not the best and they break easy. Also use a bunch of anchors; especially if having any significant amount of weight hanging on the panels. Again, use your imagination and you won’t be disappointed. I even added a couple of the small panels to my safe door to hang a couple of small AR’s and shelves.

Phenomenal Product -easy to install-provides organization beyond original safe. So easy to protect each rifle -adjustable sizing allows storing rifles with optics safe from unnecessary handling

Easily installed into my safe. Had to trim the anchors to fit my wall thickness. Love the organization and ease of accessing my firearms.

Great kit for improving your gun safe. Just make sure all the parts like the small set screws for the cradles are present.

Aurora from customer service was amazing. She helped me expedite in order and it arrived exactly on time. Made my weekend.

Expensive but a good setup with options. They no longer include the bungie cords. The metal is the way to go. I guess plastic is OK if all your doing is rifles and your not planning on future expansion but if you spent all that money on the firearms why not spend the extra couple dollars for the metal plate package.

After the retrofit, my safe is my Zen space. My mind is at ease when I look into my safe.

Customer loved the set up. Do wish the elastic barrel holders came with the kit. The location we set up in was just 14 inches deep and the extra security would be nice and recommended. Thanks

I was hesitant due to the $400 for the retrofit kit w /shipping. But it looks bad@$$ retrofitted in my TA50 gear locker. I love it and will probably order some smaller panels for handgun storage soon. Zero regrets!
