SWEEP LATCH ON POUND ON HANDLE REPLACEMENT: Each latch is
attached to the pound-on handle with a rivet through a nylon sleeve in the center.
If the latch becomes damaged, carefully drill out the rivet head and attach the
new latch using a suitable pop rivet.
This latch is secured to unbanded vent glass with two screws through holes in the glass. NOTE: The
screws are actually held by a threaded binding post on the backside of the
glass. In addition, there are various spacers and sleeves that also must be
used in this assembly. Thus, it is important that the vent glass be pushed as
close to the mullion as possible during replacement. This will keep the pieces
on the backside of the glass from coming loose, which could make latch
replacement more complicated. Remove the two screws inside the latch housing
using a suitable Phillips head screwdriver. Discard the defective latch. Place
and align the new latch and the flat handle spacer with the binding posts in
the holes through the glass. Secure in place with the screws provided. Be sure
the screws are tight, but do not use a power screwdriver. Tighten by hand.
Check for ease of operation and secure latching.
