Base Mouldings (Moldings) & Base Caps
Base Caps:
Base Caps are added to the top of an s4s board to enlarge and/or decorate the base molding. An s4s or "1 by" is a flat square board that
can be found at any lumber yard or home store. The "1 by" can have a nominal designation of 1 x 4, which has actual dimentions 1/4" thinner
and 1/2" narrower, so a 1 x 4 is actually 3/4" thick x 3-1/2" wide, s4s.
BC 151, BC 50, BC 51 and BC 52 can be added to standard s4s lumber to form a decorative base moulding of almost any height.
For a very large base, BC 57 (4-7/8") can be added to a s4s board to make it even larger.
