How to avoid the duct tape stickiness on poles

I don't like sticky duct tape residue stuck to my hiking sticks. So, to prevent my Keeper strings knots from sliding down my slippery hiking poles (or to mark where to attach tarp lines), I just rolled a 7/16" faucet O ring up the pole to the desired height to act as a stop. Available at any hardware store in the sink repair section. Cheap, light, infinitely adjustable, and works perfectly.
