DESCRIPTION
The PP350 and PP351 mounts were designed for outdoor use with small-size pendant domes,
and the PP450 and PP451 are for outdoor use with medium-size pendant domes. The PP350
and PP450 models mount to parapets, while the PP351 and PP451 models mount to rooftops
or other smooth horizontal surfaces. All models accommodate domes that use 1.5-inch NPT
pipe.
The PP450 and PP451 can be used in applications where mounting and height clearances of
models PP350 and PP351 are inadequate. Models PP450 and PP451 are higher by 9.72
inches (24.69 cm) and the overhang is increased by 14.77 inches (37.52 cm).
The mounts are designed to swivel within available clearance limits, which adds to the flexibility,
easy maintenance, and usability of the configuration.
Manufactured from aluminum, the mounts include indexing bolts to secure the arm in position.

INSTALLATION
Before Beginning
The hardware to install the mount depends on your installation requirements. The mount has
pre-drilled holes for use with 3/8-16 type hardware. (This hardware is not included with the
mount.) Use as many of the mounting holes as possible. Pelco recommends 3/8-16 type fasten-
ing hardware. Multiple fastening positions facilitate mounting flexibility. For models PP350 and
PP450, mount using a minimum of three fasteners on each side of the mounting plate. For
models PP351 and PP451, mount using a minimum of two fasteners on each side of the
mounting base. If necessary to prevent damage from water leakage, you should also have seal-
ant (not supplied) to apply around the bolt holes between the mount and mounting surface.
