Mab7 as you probably are going to do. I would put black felt strips on the hooks. Keep from scratching your guns.
This rack has a limited degree of security. he cabinet at the bottom opens with a key. Then, the vertical bar in front on the left can be lifted and the rifle removed from the rack.The wooden security bar can easily be broken to access the rifles. I have thought of substituting a metal security bar, but the firearms are located in a secure area with a metal, double deadbolt entrance door. Ron
