Venstar VSACC0620 Lock Ring Cover

Optimize your commercial or high-traffic residential thermostat installations with the Venstar VSACC0620 Lock Ring Cover. This genuine OEM component is the engineered direct replacement for the Totaline P374-0620 and 33CSLKCVR-01, providing a precise fit for Venstar Slimline Platinum series thermostats. Constructed from high-impact, UV-resistant plastic, this locking ring is designed to provide mechanical security, preventing unauthorized access to the internal wiring and the thermostat’s front door. For facility managers and HVAC contractors, it ensures that setpoints remain protected while still allowing essential access to override and temperature adjustment buttons on commercial models.

The Venstar thermostat locking cover facilitates a professional finish for T1700, T1800, T1900, T2700, T2800, and T2900 models without requiring system downtime. Installation is streamlined for field technicians; the ring slides directly onto the thermostat base without the need to disconnect terminal wiring or remove the subbase from the wall. This HVAC security accessory is essential for maintaining commissioning integrity in schools, retail environments, and multi-family housing where tamper-resistant controls are mandatory.
