Replacing a FUHR Roller-Style Multipoint Lock with HOPPE Roller-Style Lock

Replacing a FUHR Roller-Style Multipoint Lock with HOPPE Roller-Style Lock

FUHR no longer ships its products to the United States, and direct replacements for FUHR products are not readily available. All About Doors and Windows can help you find a replacement for your FUHR multipoint lock.

This article pertains specifically to replacing an automatic- or manual-style FUHR multipoint lock with two locking rollers (automatic version has an additional third stationary roller that triggers the locking motion). This tutorial will detail how to remove the original FUHR lock and replace with a HOPPE manual-operation multipoint lock with two locking rollers.

If you haven't ordered a replacement part yet, find it below. For replacement part number, look below to find original lock part number and its corresponding replacement (click on "picture" to see diagram of original FUHR lock):

The replacement process is the same for all of the above locks. The differences between the HOPPE replacement and original FUHR lock are shown in a diagram at the end of this tutorial.

HOPPE replacement comes in 2 parts, as shown at right: A) Lock gear with lower extension attached and B) Top extension

Summary of Replacement Process (Detailed Steps Follow)

  1. Remove existing lock
  2. Trim bottom of new lock if necessary
  3. Trim top extension of new lock if necessary
  4. Attach upper extension
  5. Install lock
  6. Modify or replace deadbolt strike
  7. Move top roller strike plate if necessary

Detailed Steps:

First Things First: Remove the Old Lock
  1. Use a pencil to mark height of handle on edge of door panel before removing lock. There is an alignment line on the faceplate of the lock. New lock has to be at the same handle height for rollers to line up with jamb-side strikes.
  2. Loosen set screws on base of handles and remove handles.
  3. Remove interior/exterior escutcheon plates.
  4. Unscrew cylinder screw on door edge (where latch is located), and remove cylinder.
  5. Lock runs entire length of vertical edge of door. Remove all screws.
  6. Remove the multipoint lock from the door edge.
  7. Attach upper extension of new lock to new lock body (picture below).

  1. Line up new lock with old lock so handle alignment lines are matched up; note dimension differences and similarities:
    • Lock bodies are similar length and width
    • Deadbolts are different widths and in different locations
    • New HOPPE lock is taller than original FUHR
    • Distance from bottom of lock to handle on new HOPPE lock may be shorter or longer than original lock
    • Position of top and bottom rollers on new lock should be within an inch and a half of rollers on old lock
    • If original FUHR lock was an automatic lock, you will note that the new HOPPE lock does not have an auto-release roller just above the handle
    • HOPPE locks come with a mishandling device, located between the deadbolt and spring latch, which keeps the locks from engaging unless door is closed (mishandling device is depressed); mishandling device prevents the lock from banging up the door jamb
Trim That Lock (if you need to)

The new lock will fit in your door. You might have to make some modifications first, though.

  1. If lock is too long on bottom: on door edge, measure from alignment line made in step 1 to bottom of door panel. On lock, take a permanent marker and mark on the lock the same measurement. The lock needs to be trimmed at this mark with a hacksaw.
  2. If lock is too tall on top: Set lock in door so alignment line is lined up with mark made on door's edge in step 1. Use a Permanent marker to mark where the top of the door panel hits the lock. Trim the top end of the extension to length with a hacksaw.
  3. If lock is too short on bottom: Install lock as instructed below. Once you've installed the lock, there will be a small portion of exposed mortise on the bottom of the door edge. Having extra space at the bottom and top of your door will not affect the lock. To fix the cosmetic issue if you don't like the way it looks, trim a portion of the extra faceplate removed from the top extension to fit the gap at the bottom of the door panel. This can be screwed or glued in place.

**NOTE: It is reccommended that you use a hacksaw when cutting the top extension to length. A circular saw will generate heat and cause the metal to change color. Use extreme caution when trimming lock. Have another person hold the extension or use a clamp and pliers to hold the extension to a table or workbench while trimming. Extension will be hot during and after cutting. Use sandpaper or a file to smooth cut edges.

Installation
  1. Place lock body in mortise (big hole in edge of door). Align handle height to mark made at alignment mark of old FUHR lock handle height. Install one or two screws to check operation before installing the rest of the screws.
  2. To check operation: insert a handle and spindle into the lock. Rollers should engage (move down) when handle is cocked up. Keep door open while doing this. If door is closed and lock doesn't function correctly, you may not be able to open your door. To check lock while open, push down on mishandling device between deadbolt and spring latch or lock will not work.
  3. If door functions properly, tighten and install all screws running up and down length of faceplate.
  4. Reinstall interior and exterior escutcheon plates, cylinder and handles.
Making the Strike Plates Work

Because the deadbolt is in a different spot on the new HOPPE lock, the deabolt strike plate needs modification or replacement. All About Doors & Windows has assorted finishes of HOPPE strike plates available on our website here: HOPPE strike plates

Your FUHR dead bolt strike plate can be reused. Reusing may require just moving strike plate up or down within door jamb or enlarging deadbolt hole using a hacksaw, rotozip or file.

If replacing the deadbolt strike plate, the door jamb may require some mortising to make the strike plate fit level in the jamb. If the jamb is mortised, there will be some exposed cut-out where the original strike plate was located.

The bottom roller strike plate should be in the correct location for the new lock, although the top roller strike may need to be moved up or down in the jamb. Use a pencil to mark where rollers line up with door jamb. Use a chisel or rotozip to create a new mortise or to enlarge current mortise to fit strike.

Existing roller strikes at top and bottom of door jamb (pictured at right) can be reused. Replacements are available (part #8785003), but they don't change the function or operation of the lock and may still require additional modification of the door jamb.

Operating New Lock
  1. Close door and lift handle to engage rollers in strikes.
  2. Twist thumbturn to engage deadbolt lock.
  3. Unlock from inside by twisting the thumbturn and pushing down on handle; unlock from outside using key and pushing down on handle.
