Replacement cam for Lockjack 12-13mm

Description

Replacement 12-13mm Cam for all versions of Lockjack.

The Replacement Cam for LockJack 12‑13 mm keeps your ART LockJack operating smoothly and safely. Designed to fit LockJack devices that work with 12–13 mm climbing ropes, this replacement cam restores reliable rope grip and helps maintain peak performance as the original cam wears over time.

Climbing ropes pick up grit, dirt, sap and debris during regular use. That debris can wear the original cam on your LockJack and reduce its holding power. Over time, this wear can lead to slippage or inconsistent performance. Installing a new replacement cam restores the device’s gripping surface and extends the life of your LockJack, so you can continue using it with confidence.

This replacement cam fits the ART LockJack mechanical rope control device and suits rope diameters from 12 mm to 13 mm. It installs quickly and gives you a fresh contact surface that helps the device grab and hold your rope securely during ascents, descents, and repositioning.

Made from durable aluminium with a hard, abrasion‑resistant working face, this cam stands up to repeated use in demanding environments. Regular replacement of the cam helps keep friction consistent and prevents unexpected wear from reducing performance.

Whether you’re a professional arborist, rope access technician, or experienced tree climber relying on your LockJack for friction control, this Replacement Cam for LockJack 12‑13 mm gives you a cost‑effective way to keep your gear in top condition. Installing a new cam is a simple maintenance step that enhances safety, improves rope handling, and helps your LockJack perform as designed over the long haul.
