Exactly what skintback said with the cam buckle. Now add a rope ratchet instead of a plain rope, best thing I've ever come up with. You can get one at lowe's that comes with 8' of 3/8" rope on it. It holds 250# I think, but anyway, I removed the short rope and bought a roll of 100' 3/8" rope. This rope doesn't have a lot of weight capacity but the loc ons don't weigh that much anyway. I then cut about 30' off to replace the short one.

Get you a linesmans belt so you use both hands to mount the stand, attach the rope to the stand and the ratchet part to you. Now climb up the tree or stick ladder and attach the linesman belt then attach the slip cam about 3' or so above where you want the stand mounted. Attach the ratchet to the eye of the slip cam and start pulling.

The good thing about the ratchet is it locks as you pull the rope thru like a chain hoist, makes a clicking noise as you pull but makes putting up a loc on a breeze.
