Kadee O-SCALE 811 Installation Instructions

INSTALLATION INSTRUCTIONS for the No. 811 DELAYED uncoupler -
read complete instructions before starting.
The No. 811 uncoupler is Delayed. It is to be used with Kadee O scale
couplers.
Permanent magnet
mounts between rails
TO MOUNT:
This uncoupler must be mounted exactly in the center of the track so first
find the center between the rails and mark it. The uncoupler magnet should
at no point extend above the rails by more than 3/64 inch. In most
instances all that is necessary for proper installation is to glue it in the
center of the roadbed. However, if it doesn't you will have to cut out a
section of ties the exact width and length of the magnet. The depth of the
section that you cut out should be gauged so when the magnet is in position
it sticks up above the railtop 3/64 of an inch.
The amount you will cut out of the ties will depend on which of the dif-
ferent code rails, with their various code heights, you will be using.
Use white glue to anchor metal plate and magnet in roadbed. Remember,
the metal plate must be placed under the magnet (not on top of it) for
proper operation.
