Our new HIT-66-210 template is designed to quickly and accurately install or retrofit the Alarm Lock DL3500 series mortise locks. All required holes are lined with hardened drill bushings, the larger holes for mortise cylinder and lever spindle will also accept hole saws.  The wire run hole is adjustable for both fire rated and non-fire rated doors.  Plates are machined from aluminum and hard anodized.  This template requires the HIT-66 clamp system that includes the HIT-4509 mortise alignment plate (HIT-66 clamp system sold separately). The template set includes both inside and outside template guides. All drill guide holes are identified for trouble free drilling. Door range for the HIT-66 clamp system is 1-1/4” to 2-7/8”.
