SpiderJack 3 Replacement Parts

SpiderJack 3 replacement parts let you swap worn components on ART's mechanical friction device for MRS climbing instead of retiring the whole unit. Wear parts are part of owning any device that rope runs through all day.

Why parts wear

The SpiderJack 3 manages friction on a moving rope system with metal parts that the rope bears on all day. Rope carries grit and bark into the device, and over time that grinds down contact surfaces. Springs, pins and similar parts can also wear or get damaged in normal use.

ART designed the device to be maintained, so worn parts can be replaced rather than retiring the whole unit. Browse other MRS devices and accessories.

Keeping a spare of the parts that wear first in the truck can save a lost day if one fails inspection at the start of a climb. Ask the seller which parts ship together and which are sold individually.

Replacing parts safely

Identify the exact part you need from the manufacturer's documentation and make sure it is for the SpiderJack 3, not an earlier version. Follow ART's instructions for replacement, and if the instructions say a part must be fitted by the manufacturer or a competent person, follow that.

After any repair, check the device function close to the ground before climbing on it. Life-support gear must meet the applicable standard, be used per ANSI Z133 and the manufacturer's instructions, and be inspected before every climb by a trained user. Retire the device when ART's instructions say it is worn beyond service.

Clean the device as the manufacturer directs, especially after climbing on muddy or sappy rope, since grit speeds wear on every contact surface.
