I like my CB-6K, but have always had two problems with it: 1. Pull-out is possible 2. Morning wood For me, this CB-xK belt seems to help with both. I've heard mention of doing this a while back, but I've never seen it documented so I decided to share that others might be able to benefit. This is a really simple removable modification, and nearly anyone should be able to do it. It's made with two components: 3/8" welded-link chain, 3/8" ID vinyl tubing Tools: Sharp utility knife or small pair of scissors; bolt cutter, dremel tool with cutting disc or a hacksaw I cut the hose about 6" too long and the chain slightly longer, and threaded the chain through it. It was a really tight fit, so it was a bit tricky getting the chain threaded through the hose. I used a vacuum cleaner to suck some nylon pull-cord (used for pulling phone/cableTV/data cables through walls) through the tube, tied it to the chain and tied the other end to something immovable (my Mistress). I put some silicon lube in the tube to make it slick, and started massaging the tube down the length of the chain. Once it was all the way through, I did some test fitting, and cut the tube so it was a little closer to length (snug) using a small, sharp pair of scissors. I still have yet to cut the chain, as you can see by the little bit dangling down behind the tube in the first photo, but it really hasn't been a problem. I got the supplies at my local Home Depot, and I think the total cost was something like $8-$10 for 4' of chain and 10' of hose. I believe the chain is electro-galvanized, so it should resist rust, and it doesn't come into contact with my skin because of the hose. The only thing I worry a little about is that skin oils might break down the hose since its vinyl, but I don't really know whether vinyl is supsceptible to oil or not. The pics below show how it attaches to my CB-6K and a closeup of the chain.
