Kayak Pulley Kit,Heavy Duty Kayak Slide Rail Anchor Trolley Kit Pulley Blocks Sheave for Kayak Canoe Boat - 2 Pack

Mounted this on my trolling motor to raise and lower it on the back of my kayak. Sturdy, and it works well.

I was a bit surprised to find lightweight plastic "bearings" in the pulley. Hopefully, they'll stand up. They're not sealed so some sand could get in with them and probably cause some damage. Other than that...the pulleys aren't bad and should do a decent job on very light weight applications.

Works very smoothly, the fit and finish is not usually found today.

This is exactly what I had been looking for. All the anchor trolley kits out there are designed to be bolted on. I attached these using a special loctite adhesive for plastics and it was so easy. I have anchored in severe wind with no issues. Flush and smooth, great pulleys!

Worked for what I needed, I'm not sure I would trust it over 50 pounds. I did take out the bolts and punched longer ones so I could hardmount it onto my kayak. I will warn you, if you take theose bolts out and pull it a apart, you are doing to have a fine time putting a bunch of small plastic bearing back in.Overall I would recommend it for lighter applications, good for the price.

These pulleys are made of tough plastic or nylon and two short stainless steel bolts which are non-resonant at Ham Radio frequencies. I used four of these to suspend the corners of full wavelength / multiple wavelength loop antennas (like 40m or 135' of wire, or larger). The sheave (pulley wheel) is so close to the frame of the pulley that even small gauge wire cannot slip between them accidentally (I used Amazon's tough MS135 18-gauge stealth wire) yet the wheel spins freely on tough plastic ball bearings. Do NOT open the sheave bolt or you will spill the ball bearings -- you may loosen it slightly, however. If you remove the top bolt you can pry open the frame a little (there is a small mating detent) and pivot the two frame halves apart to install it on an existing wire. Use a screw-mount style tie wrap around the top bolt frame to create a means to support the pulley with a rope. Add a stainless steel saltwater-rated fishing line swivel to the pulley tie-wrap to allow the pulley to untwist the wire easily (Amazon: Size-8 swivel, 220 lb, 33mm is a good size to work with).

Works better than expected

These pulleys are great for an anchor trolly. The way they come there is no way to mount them, but if you take the screw out that doesn't go threw the actual wheel, you can use that hole to put in a longer bolt to mount with. The whole assembly is about 5/8th of an inch thick so its a little too thick to mount with a rivet. If you take out both screws at the same time the assembly breaks in half and you loose all the little plastic bearings so be careful.
