ROLYPULLEY / PULLEYS FOR FLAT WEBBING
RolyPulley
RolyPulley is the pulley made for flat webbing. Thread a strap over a stainless roller to change direction, lift gear, or take up tension the way you would with rope.
Why use a flat strap? Webbing stays low-profile, lies across a broader surface than round rope, makes twists easy to see, and works naturally with buckles and bolt-on hardware. Choose 1-inch or 1.25-inch pulleys, ready-made kits, LaserWeb straps, and individual replacement parts.
The strength of a complete setup depends on the selected webbing, anchors, hardware, layout, installation, and intended use.
01 / 1-INCH SYSTEMS
Start with the everyday strap size.
Our 1-inch pulleys and matching webbing make a compact starting point.02 / 1.25-INCH SYSTEMS
Choose a wider strap when the layout calls for it.
The 1.25-inch family offers the same pulley choices in a wider webbing format.03 / WEBBING + SERVICE PARTS
Control the strap. Replace the small parts.
Rollercam buckles, WebWashers, WebCotters, rollers, pins, and rings stay with the strap path.04 / FEATURED KIT / CHANGE DIRECTION
Two pulleys. One pivot point.
Join two compatible RolyPulleys back to back so each one can carry a different strap direction. The shared hardware stack lets the pair turn instead of forcing the webbing into one fixed angle.
- 01Face two compatible pulley bodies back to back.
- 02Join them with the low-profile five-piece hardware stack.
- 03Let the pair turn to follow the direction of the straps.
05 / CONTROL THE STRAP
Lock the strap where you want it.
The black Rollercam is the simple, hand-operated control point for a RolyPulley webbing path. Pull the flat strap through to adjust it, then let the roller and cam hold the position.

06 / FINE-TUNE THE STRAP
Take up slack with one simple turn.
Swap a compatible roller for the WebCotter, pass the webbing through its center, and turn it with an Allen key. The strap winds around the pin so you can remove slack before the Rollercam holds it in place.
