Restraint Pin Socket

Groxx Restraint Pin Receiver Socket | GGRXTB38 Structural Mounting Socket
The Groxx Restraint Pin Receiver Socket (GGRXTB38) is a high-precision structural mounting component engineered to house and secure 3/8 inch restraint pins, such as the GGRXTB37 series. Designed for flush or surface integration into facade panels, curtain walls, and heavy structural frameworks, the GGRXTB38 socket provides a seamless, high-strength connection point that facilitates rapid pin insertion and dependable multi-axis load transfer.
Core Performance & Design

Optimized Structural Receiver Geometry: Internal bore dimensions are machined to match 3/8 inch restraint pin profiles, providing a flush, zero-slop fit that eliminates chatter under dynamic loading.

High-Strength Force Transfer: Engineered to withstand and distribute axial, angular, and lateral loads up to 2.7 kN back into the primary building substrate or structural frame.

Corrosion-Resistant Metallurgy: Manufactured from high-grade stainless steel with a polished finish to prevent galvanic corrosion when integrated with aluminum facade panels or steel support structures.

Positive Lock Interface: Built to interact smoothly with the pin’s lower mechanical retention detents, guaranteeing a positive mechanical engagement every time the pin is fully inserted.

Installation & Structural Integration

Substrate Preparation: Ensure the mounting aperture in the facade or structural member is reamed to match the outer socket body diameter without excessive clearance.

Standoff Alignment: Mount the socket flush with the outer face to ensure the installed restraint pin maintains a structural standoff gap (X max) of 3/16 inch or less, keeping system capacity at the rated 2.7 kN.

Rigid Fixing: Can be integrated directly into curtain wall aluminum extrusions, steel plates, or cast-in concrete anchors.

The Groxx Advantage
The GGRXTB38 Socket completes the restraint pin assembly by offering a perfectly matched, wear-resistant receiver. By maintaining exact tolerances and superior surface finish, Groxx ensures smooth pin insertion, reliable locking detent engagement, and uncompromised safety performance across all 3 loading axes.
