SDCJ Incremental Bottom Plate — Replacement

Replacement incremental bottom plate for the Anchor Bolt Locating Jig (Shields Dead Center Jig, SDCJ). The bottom plate seats the jig over your anchor bolt, so you match the plate to the bolt you are shooting. Plates run from 1/2 inch to 1-7/8 inch in 1/8 inch increments, and a separate Plumbing Plate variant carries the laser vertical reference. Match a worn or cracked plate's size to drop in a fresh one, or add sizes to cover more bolt diameters. Manufactured from ASA for strength and UV resistance.
