Wow... I’m still going to try it... but I’m not getting rid of my superclamps. I manage to make a bigger adjustable knob ( sled locxx) and made it so I can lock it.. you won’t be able to unscrew the adjustment.
I just picked up the Sled Locxx today, will be testing it this coming season... I currently have 2 superclamp II and notice that they would move a bit... not sure if it’s the ski design that make the sled move or not... had the rear clamps as well, only use them twice... they don’t work well on...
I build this using the same shelving that they have at Costco, it all come apart so in the winter time it's not in the way also I got caster wheels so I can move it where ever I want. I use my sled deck ramp to put the top one.... never got a chance to rig up the winch yet... Also a lot cheeper...
