SMC Apex Pulley 1.5

The SMC Apex Pulley 1.5 is the standard Apex in the larger 1.5 size, with a bigger sheave than the 1.1 for smoother running under load. Tree crews use it in pull systems, redirects, and light rigging where a micro pulley is too small.

Apex vs. Apex Direct

SMC sells the Apex in more than one style, and the Apex Direct is a close cousin rather than this exact pulley. This is the standard Apex in the 1.5 size. Both share the larger sheave, so the choice usually comes down to how the side plates open and how the pulley clips into your system. Check the listing photos and the side-plate markings before you buy a replacement to match a kit.

Using it on tree work

A 1.5 size pulley is a good middle ground for crews. It is light enough to carry up the tree for a redirect, and the bigger sheave makes a noticeable difference when you are pulling a 3:1 to tension a felling line or hauling a saw to the climber.

It is not a rigging block. Do not use it to block down heavy wood or take shock loads. Spin the sheave before each use, look for cracks, burrs or play at the axle, and clean out sap and grit. Retire it after a hard drop unless SMC says otherwise. Life-support use must follow ANSI Z133, the manufacturer's instructions, and your training, and the gear should be inspected before every climb.
