Our new HIT-66-252 template is designed to quickly and accurately install or retrofit the KABA ILCO 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.  All drill locations are identified for easy identification.  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. Door range for the HIT-66 clamp system is 1-1/4” to 2-7/8”.
