Strap-On Harness Guide

O-rings, snaps, and docking plates

Compare attachment systems before matching accessories.

Measure the mount

An O-ring needs a compatible accessory diameter and base. A snap system depends on matching fasteners. A suction dock depends on the type and dimensions of the accessory base.

Check the exact listing

The phrase universal fit does not tell you the opening size. Read the manufacturer’s compatibility information and check the parts in the selected package.
