SDC's 45 series 5/8" latchbolt electric strikes are centerline latch entry strikes designed for use with cylindrical locksets and mortise locksets without deadbolt for both metal and wood frames. 45 Series strikes accept 5/8" throw latchbolts or up to 3/4" throw latchbolts with 1/8" door gap. 45F Models are fire-rated and accept 9/16" throw latchbolts or up to 5/8" throw latchbolts with 1/8" door gap. Built with all stainless steel parts, a durable die-cast body and fewer moving parts for maximum lifespan and corrosion resistance, the quality construction makes 45 series strikes ideal for high traffic applications. The compact low-profile design enables quick and easy installation where jamb space is limited. Centerline latch entry strikes require the latch to enter at the strike "centerline" located exactly between the top and bottom of the strike faceplate.
