Popular Installation Templates

  • Von Duprin 98/99 exit device templates

  • Best 45H mortise lock templates
  • Plug followers for cylinder removal and rekeying
  • Pinning trays and kits for driver and key pins

FAQs

What is a Von Duprin 98 template used for? It provides the precise door and frame prep for installing a Von Duprin 98 series rim exit device — hole locations, dimensions, and mounting points specific to that series.

Is the Von Duprin 99 template the same as the 98 template? No. The 98 and 99 series use different door preps in some configurations — always confirm your exact device series before ordering a template to avoid a misaligned installation.

Is the Schlage L9080 template the same as other Schlage L Series templates? The L9080 shares the core L Series door prep but has function-specific variations. Confirm the exact model before cutting the door.

Do I need a jig to install a Best 45H mortise lock? Not required, but strongly recommended — a template ensures precise hole placement and prevents misalignment between the latch and strike.

Why use a template instead of measuring by hand? Mortise lock and exit device preps require multiple aligned cutouts. A manufacturer template guarantees the latch, strike, and trim line up correctly the first time, avoiding a redo on an expensive commercial door.
