HINGED WALK-IN DOORS
Replacing the D-1000 touch latch on Walk-Ins
A. Remove the defective latch assembly. First remove the handle spring clip from under the handle at the
back of the latch base, using a pair of needle-nose pliers. See Figure 4.
B. Using a hammer and punch, drive out and remove the latch handle pin from the handle. Remove the three
¼-20 oval-head machine screws from the latch base and remove the base.
C. From the inside of the Walk-In, drill out the roll pin from the safety release handle and remove the handle.
(Doors prior to 1995) Current production doors are provided with an interior mounted safety knob which
is threaded directly onto the strike bolt. Loosen the allen screw located in the side of the knob using a
5/32 allen key and turn counter clockwise until disengaged from the strike bolt. Pull the strike bolt from
the outside away from the Walk-In wall. The strike plate will fall away.
D. Secure the new D-1000 latch base to the Walk-In door with three ¼-20 oval-head machine screws.
E. Insert the new strike bolt with attached strike plate into the holes on the door jamb panel.
F. Screw the new inside knob onto the strike bolt until adequate tension is applied to the rod to hold the
assembly firmly in place. Tighten the set screw on the side of the knob using a 5/32 allen key to allow for
¼ turn safety release operation Check to be certain that the “T” rod rotates freely when turning the inside
knob.
G. Insert the latch handle spring into the indicated hole on the latch base. Slip the latch handle over the latch
base and align all holes. Be sure the latch handle spring engages the latch handle tab on the underside of
the handle. Insert the latch handle pin through the handle and base. Using needle-nose pliers, insert the
spring clip through the slot in the latch base assembly. Make certain to align the slot in the latch handle
pin with the slot in the base before inserting the clip. This will firmly secure the latch handle in place for
use.
H. Open and close the door several times to assure proper operation of the latch.
