APPLYING INSTALLATION FINS		$VU UP MFOHUI VTJOH
A. Cut the fins to length. Using the following	A"	HJWFO	GPSNVMB
formula, cut the fins to length, making sure
the end cut is square on both ends.

Heads and Sills: Length = Frame width + 2-1/2"

Jambs: Length = Frame height + 2-1/2"

Jambs, if there is no fin at the sill: Length = Frame height + 1-1/4"

Combinations: Length = Combination height + 2-1/2"

B. Notch the ends of the fins. Measure and	B#
mark 1-7/16" from each end of the fins. Using
a hacksaw, cut the fin receptor leg at the mark.
Finish removing the bottom receptor legs by
scoring the fin with a utility knife and snapping it	
off the fin.

Note: When using fins on all four sides, all ends must be notched. If no fin is used at the sill, DO NOT notch the bottom of the jamb fins.
