SECURITRON MODEL UHB, UHB-82 UNIVERSAL HEADER BRACKET
INSTALLATION INSTRUCTIONS
1. DESCRIPTION
The model UHB bracket is used with the model 62 or model 32 Magnalock for installations where the door
header is not wide enough to accommodate the magnet (commonly the case with aluminum frame glass
doors). A longer version (UHB-82) is used with the model 82 Magnalock. The bracket can be mounted in
either of two orientations to yield the strongest and most attractive installation. It also allows concealment
of the Magnalock wire cable which contributes to security and appearance. Finally, the bracket has a 2nd use
as a splice chamber which can mount electronic accessories as explained in Section 3. U.S. and metric
(UHBM) versions are available as are two finishes: CL (clear aluminum) and BK (black aluminum).
2. MOUNTING
Note that the bracket can be positioned vertically or horizontally to yield a 1" or 1 1/2" (25 or 58MM)
extension to the header. The choice depends on how far the header needs to be extended to fit the magnet.
Extending the header only 1" (vertical position of bracket) yields a stronger installation and so we
recommend this unless a greater extension is required.
Refer to Figure 4 of the Magnalock instructions for a view showing the positioning of the bracket. Note that
the stop filler plate is usually not required. Many aluminum frame glass doors have no stops and in other
cases, the stop is a "blade" type which can be cut away.
Generally the first installation step is to drill a hole in the header for wire pulling and then drill a matching
hole in the bracket. You then mount the bracket to the header following the drawing shown on Page 2. The
blind nuts are collapsed with either the tool packed with Magnalocks or with Securitron's blind nut collapsing
tool (part of the Magnalock installation tool kit).
With the bracket mounted, the magnet can now be mounted to the header and bracket following the
template and Magnalock instructions. For the model 62 or 82, the magnet front screws will ideally enter the
header directly and the rear screws will enter the bracket with the cable also entering the bracket. Two other
possibilities exist. All four screws may enter the bracket if the header is quite narrow, or the Magnalock front
screws may fall on the intersection of the bracket and the header. In the latter case, it is acceptable to use
only the back mounting screws on aluminum frame glass doors. On such doors, however, the close point can
be adjusted to allow use of all 4 screws unless there is a dead lock which will still be in use. Note that we
supply two shorter (2 1/2" or 60MM) magnet mounting screws with the bracket hardware pack. If these
screws are used for magnet to bracket mounting, they block the bracket interior less than the 3" (75MM)
screws supplied with the Magnalock which makes wire splicing easier. The model 32 has only two magnet
mounting screws so its case is simpler than the one described above.
Note that the bracket is longer than the magnet which provides installation flexibility. The final step after all
screws are secure is to tap in the tamper caps. Note that the caps go in with difficulty which makes them
more secure. We advise driving them in gently with numerous hammer taps so as to avoid the possibility of
bending the bracket. The large rectangular caps which seal the end of the bracket are best driven in with
two hammers striking both ends of the bracket at the same time. This avoids pressuring the mounting
screws by hitting one side at a time. You'll find that if the magnet is centered on the bracket, both
rectangular end caps go in cleanly. If, however, you've chosen to offset the magnet on the bracket, the
magnet mounting screw will interfere with the end cap. To deal with this, cut away part of the inside of the
end cap with a nipper to clear the mounting screw.
