Say hello to the all new BC Roller, a webbing pulley carabiner designed for tensioning Slacklines and rolling across highlines. This carabiner is lightweight, durable, and fits well with most hardware. We have an option of either a straight gate or a 2-stage twist-lock gate.

A great size roller for the harness or tensioning system.

One of the primary drivers when designing the BC Roller was to keep the weight low and the size small. We accomplished that quite well with a mere 121 gram total weight and 120mm x 66.2mm x 20mm size. These dimensions make the BC Roller fit quite nicely on the harness and a breeze to work with at the anchors.

Don't let the small outer dimensions fool you though, the BC Roller has a TON of room inside the carabiner. Passing connections, clipping large lines, and clipping hardware is a breeze with this carabiner. The straight gate model has a whopping 28.5mm of space when the gate is open.

All models come with stainless steel bearings.

You never know when you will be highlining or using your gear in a high-corrosion environment, like near the ocean or sea. Having non-stainless steel bearings in any type of pulley is just asking for troubles. We made the decision to include stainless steel bearings in all models of the BC Roller. This will help the lifespan of your roller, no matter what environment you decide to use it in.

An ideal component in the widely used Buckingham tensioning system. 

Whether you are rigging a highline that's 2km long, or a simply park line, the Buckingham system is a great way to tension your line. Using a roller such as the BC Roller, a weblock (AWL6), a webbing grip (Wafer XL), and a soft release, you can tension slacklines of pretty much any length.

Safety Information

The BC Roller is NOT certified as PPE. It cannot be relied on as a single component when used as a tether. An additional tether must always be present.

The BC Roller is meant for tensioning slacklines and transporting a single person across a highline. It is not meant for any other uses.
