The P7-IL Auto-Adjust Dog Peg Clamps were developed as an extension of prior work in self-adjusting clamping systems and track-based workholding solutions. The platform builds on the foundation of Self-Adjusting Toggle Clamps (STCs) developed for BESSEY, combined with die-cast T-Track clamp architectures developed for the patent holders.

The In-Line variant is based on a scaled 0.7 Cam-Lock mechanism derived from the STC platform, with a key distinction. In a redefinition of the mechanism by the Pooles, the Bar functions as the primary force output element rather than an articulated Jaw.

The “Gen2” program marked the first implementation of the 0.7 and 0.5 scale Cam-Lock mechanisms in die-cast ZAMAK (zinc alloy) architecture, replacing stamped/formed, heat-treated, and plated medium carbon steel constructions. Die-casting also allowed for functional and IP advancements not possible with stamped/formed steel. Mike’s role was to engineer and design structures tailored for T-track and dog hole applications. Given the high clamping forces generated, this introduced material and durability risk relative to prior billet aluminum prototypes produced at PDI. That risk was mitigated through extensive cycle testing, with additional stress validation conducted by Craftsman and Rockler in-house R&D as part of a private label program launched during Armor Tool’s early development.
