Tube size fits the keppi 5000. A tungsten drill bit and my drill press solved the pin alignment issue. A little bit of wiggle in the vertical shaft (not related to the bench). It's solid and uses the grippy new vinyl, and comfortable. Like others have said, it's the only option for a quality 3rd party preacher bench attachment. Fortunately the pricing is reasonable. Would recommend if you are space conscious and have a rep or similar bench.

The first piece of gear I purchased, at it's launch, a few years ago on amazon before being aware of rep and all the controversy. Bench is solid as a rock. If you understand how to use tighten-able pop-pins you should have no problem putting up weight very comfortably. The front handle is awkward and I hate how easily the end caps come off. Beyond that, controversy aside, I would have recommended this bench. I like the zero gap system, but honestly not what sold me on it. It does make the bench a bit more comfortable than my other bench when having to use the bench in unconventional positions.

I thought this would be decent for replacing my normal V bar and ended up replacing several attachments. great for close grip pull downs, overhead tricep work, curls, pushdowns. I really like this piece. knurling is very comfortable and so much better than cheap rubber grips. considering the price point and quality, I'd recommend this attachment to anyone with cables.

From a quality/performance standpoint I definitely lucked out. no deformations, all printing was good. the collars have retained their shape well. considering i got these for 50 cents a pounds, it's pretty hard to complain. If you are on a tight budget and understand that these are the bottom of the barrel but totally functional, these are for you. Have had them for over 2 years now

For reference, I'm 6'1", my wife is 5'2". for both press and hack squat I can almost get close to the depth I like (generally bottom out and lose tension which is jarring and annoying). I like very deep. Wife can't get any kind of depth. she has been using thick yoga pads to get closer on the hack squat. build quality is pretty solid. removing the headrest and top bar makes it much more compact. (though limits the weight capacity). having the issue with the safety dropping mid lift, which is also jarring and annoying. will likely be replacing this unit in the long run.
