STI Announces Spring Loaded Hinged Cover With Mounting Plate


STI announces this spring loaded hinged cover can take hard knocks in stride while helping to protect smaller-sized single-gang electrical units. The cover, adapter plate and hinges are molded of super tough clear polycarbonate material.


The Bopper Stopper® cover (STI-6518) and the included adapter plate provides a solid back for surface mount applications. Inexpensive and highly durable, the device features a stainless steel torsion spring to keep the cover closed.

Complete with installation screws and gasket, and backed by a three year guarantee against breakage in normal use.
