7501C - Electric Strike by HES
The 7500 Series is a Complete One Box Solution!
The 7501C Series electric strike is ideal for fire rated applications with pre-load conditions caused by a warped or misaligned door, weather stripping, a smoke seal or any other condtiion that could cause door bind. The heavy duty stainless steel construction provides the strength and durability required to accommodate fire rated latchbolts up to 3/4" throw.
What is Pre-load?
Simply stated, door preload is pressure exerted on a door, that is transfered to the keeper of the electric strike by the latch. A number of conditions can cause door preload including pressure from HVAC systems, thick door seals or heavy weatherstripping, misaligned, damaged, bent, warped doors, or user anticipation. When pressure is applied to some models of electric strikes, the keeper may not release because the pressure binds it against the latch. Door preload can prevent the smooth unlocking of the electric strike or even disable it - preventing the door from being opened.
