Our new HIT-66-251 template is designed to quickly and accurately install or retrofit the KABA 700 series mortise locks. All required holes are lined with hardened drill bushings, the larger holes for the mortise cylinder and lever spindle will also accept hole saws. Plates are machined from aluminum and anodized. This template requires the HIT-66 clamp system that includes the HIT-4509 mortise alignment plate (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”. The HIT-66-251 will work on both wood or steel doors.
