STI-1331 Clear Spacer Pull Station Cover Accessory

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-1331 is a clear spacer designed for use with universal stopper-style pull station covers. This accessory provides the necessary offset clearance between a pull station cover and the wall or mounting surface, ensuring a proper fit when installation depth or surface irregularities require additional spacing. Typically installed by fire alarm technicians or licensed electricians, the STI-1331 is a single-unit replacement part that supports clean, professional cover installations on pull station devices.

This spacer is suited for commercial and institutional fire alarm installations where pull station covers must mount flush and securely against walls, conduit boxes, or backplates with varying depths. It is commonly used during new installations and retrofit projects where existing pull stations are being brought into compliance or updated with protective covers. The unit ships individually and is intended for use with compatible universal stopper-type pull station cover assemblies.

Key Features

Installation Notes

Installation should be performed by a qualified fire alarm technician or licensed electrician in accordance with applicable local codes and NFPA 72 requirements. Before servicing any fire alarm pull station, notify the monitoring center and follow site-specific lockout procedures. Ensure the spacer is seated evenly between the cover and the mounting surface before securing fasteners. Do not overtighten fasteners, as this may crack the clear spacer material.
