Older Pella doors were manufactured with GU/Ferco shootbolt multipoint locks. Pella no longer
manufactures doors with these particular mechanisms, but we can help you replace your lock if it
breaks.

If your lock is not a GU/Ferco lock, this article will not help you. To identify
whether or not your lock is a GU/Ferco, look at the lock faceplate for the GU
or G-U/Ferco logo (shown in picture to right). It should be about 7 inches up
from the spring latch.

If this is your lock, it can be easily replaced with a new GU replacement lock,
part #4990330.

Pella original GU/Ferco lock is a three-point lock with a shootbolt at top, a
shootbolt at bottom and a deadbolt and latch at handle. Replacement lock
also has these three locking points, same handle-height (35") and same
backset (50mm).


It is important to understand the few differences between the original and new locks:

   –   One-Piece vs. Two-Piece Lock (diagram below):
          – New lock comes in two pieces: 1) Main gear, 2) top shootbolt tip
          – Most original locks were one-piece locks, although there were some 2-piece locks

   –   Deadbolt Strikeplate
          – Deadbolt and spring latch are less than
             1" lower than on the original lock; this
             means deadbolt strikeplate must be
             modified slightly (picture at left)

DETAILED STEPS:

To Replace Pella Multi-Point Lock:
   1. Remove handles and escutcheons.

                   ▪ Loosen the set screw on the interior handle with a hex wrench.

                   ▪ Use a flathead screwdriver on interior side to unscrew faceplates.

                   ▪ Remove faceplates; spindle and cylinder tailpiece will pull out with faceplates.

   2. Lock runs entire length of vertical edge of door. Remove all screws and remove multipoint lock
      from door edge.




   3. Determine how much lock needs to be trimmed to make lock fit in door panel with shootbolt
      tip*:
                ▪ Lay old lock next to replacement lock, lining up bottoms, so handles are both at
                   same height. Make sure both locks are disengaged (shootbolt tips and deadbolts
                   retracted)

                  ▪ If old lock is a two-piece, make a mark on replacement lock to match where
                    heights of locks match up (without shootbolt tips attached).




                  ▪ If old lock is a one-piece, lay shootbolt tip so top lines up with original lock top.
                    Mark on new lock where the difference must be trimmed down so lock fits in
                    door with shootbolt tip attached.

                  ▪ Option 1 if old lock is not available: Install bottom gear and secure with 1 or 2
                    screws. Place shootbolt tip at top of door and mark where alligator teeth will fit
                    into shootbolt tip. Remove lock from door and trim excess.
                  ▪ Option 2 if old lock is not available: Determine the amount to be trimmed by
                    subtracting the overall length of assembled lock, 81", from the height of your
                    door.

                     If door panel is 77-1/4" with shootbolt tip 6-3/4", the cut-off would be 3-3/4".
                     So: 81" lock – 77-1/4" height of door = 3-3/4" amount to be trimmed,
                     i.e.: 81 - 77-1/4 = 3-3/4 cut off.

*Note: See picture below. When trimming, cut can be 1/8" short; alligator teeth must fit in
connector, but connecting plate will cover up a small gap. All three placements shown in the
picture are acceptable lengths of lock.

   4. Once the measurements have been determined, mark this length to be trimmed with a sharpie on
      the lock itself.




   5. Clamp lock to table and carefully trim with hacksaw. NOTE: This step requires caution and
      knowledge of safety procedures. Watch fingers and keep children away. Extension will be
      hot during and after cutting.




   6. Use a file, sandpaper or a sander to smooth cut edge of trimmed extension piece.

   7. Slip newly trimmed lock body into mortise in door edge.

   8. Attach top shootbolt tip by fitting alligator teeth of backplate into connector on shootbolt tip.

   9. Use fingertips or a screwdriver to slide connector plate over gap between main gear and
      shootbolt.




   10. Screw lock in place in two or three places. Stick handle with spindle into lock and check
       operation with door open. Deadbolt and shootbolt should engage when handle is lifted; turning
       thumbturn should lock deadbolt, shootbolts and handle in place.

   11. If lock functions properly, unlock lock and install and tighten all screws running up and down
       length of faceplate.

   12. Close door almost completely, watching how deadbolt and spring latch line up with strike plate.
       Try lifting handle; lock and strike plate are most likely slightly off. Use pencil to mark on strike
       plate location of deadbolt and spring latch.

   13. Open door and remove strike plate.

   14. Using a rasp or file, carefully remove excess material from bottom of each hole in strike plate,
       or about 1/8".




   15. Reinstall strike plate and test operation.

   16. Reinstall faceplates and handles, making sure to tighten set screw.


*NOTE: If door is greater than 81", attach middle extension (part #40325) to main gear and trim
middle extension in the same manner as described above before attaching shootbolt tip.
