COLONIAL COLUMN CAP/BASE SPECIFICATIONS
ROUND COLONIAL TAPERED AND NON-TAPERED CAPS AND BASES
The Colonial style caps and bases are sized specifically for our wood Colonial column shafts and will not fit our other column
products.
POLYURETHANE:
The preferred cap/base for exterior
use, Poly-U-Rim™ (reaction injection
molding) components are specially
designed to provide consistent detail
and increased durability. Polyure-
thane is impervious to moisture, rot,
decay and insect damage, providing
strength, beauty and long life.
WOOD:
Finger-joint pine caps and bases are not recommended for exterior use. If these are used outdoors, an aluminum plinth is re-
quired to maintain warranty coverage. FJ pine caps and bases are treated with Woodlife® 111 (see Wood Columns and Posts
Technical Information for further details) unless specified otherwise.
