How to Trim a HOPPE Multipoint Lock to Fit Your Door (With or Without Shootbolts)

Sometimes a replacement multipoint lock is slightly longer than the door it’s going into. This guide explains where trimming is allowed, what should never be cut, and how to do it safely.

Jump to: Without Shootbolts | With Shootbolts

Key Takeaways

  • Only trim extensions, never the main lock case.
  • Shootbolt and non-shootbolt locks are trimmed differently.
  • Always confirm measurements before cutting.

Identify Your Lock Style

Look at the very top and bottom of the lock. If bolts extend into the frame, you have a shootbolt-style lock. If not, follow the non-shootbolt section below.

Trimming HOPPE Locks Without Shootbolts

On HOPPE locks without shootbolts, trimming is limited to removing excess faceplate or extension length so the lock fits the door edge correctly.

Set the Final Lock Height

  1. Place the lock into the door edge to check overall height.
  2. Insert the handle spindle to hold the lock in position.
  3. Mark any excess length extending past the door.
  4. Remove the lock, clamp it securely, and cut the excess.
  5. File the cut edge smooth.

Trimming HOPPE Locks With Shootbolts

Shootbolt-style HOPPE multipoint locks are built from multiple sections. Understanding these parts is critical before cutting.

How Shootbolt Multipoint Locks Are Built

Because door heights vary, shootbolt extensions are often supplied longer than needed and trimmed to fit. Only the extension section should ever be cut.

Before You Cut a Shootbolt Extension

  • Compare the new lock to the old lock whenever possible.
  • Measure from the center lock so the handle height stays correct.
  • Extend the shootbolt to the locked position before cutting.
  • Leave at least 1-3/4" of serration to reconnect sections securely.

If the Extension Is Cut Too Short

If the shootbolt extension is trimmed slightly short, the connection can often be stabilized using a cover plate.

A stainless steel extension cover plate can bridge the gap and help prevent the serrated section from pulling out of the sleeve connection.

Final Check Before Reinstalling

  • Confirm final lock length.
  • Smooth all cut edges.
  • Reconnect extensions securely.
  • Test shootbolt operation before reinstalling the lock.
