PREPARATION / INSTALLATION
The cut length formula for the can receptor is horizontal rough opening minus 1/2".
The can receptor system does not accommodate door jambs. If doors are a
requirement, a standard shear block storefront system will have to be used.
The use of end caps are at the discretion of the architect / general contractor.
Exterior and interior perimeter seals are mandatory with this can system.
The cut length formula for jambs and verticals is frame dimension minus .825".
Tip up the jamb in place being sure the
sill end is set in sealant maintaining a
perimeter seal between jamb, sill can, and
the condition. Fasten the jamb in place
using 1/4" diameter minimum fastener on
16" centers.
Snap-in the head and sill can fillers, locating
them tight against the jamb member.
Rotate the first vertical in place in the sill can,
locating the vertical tight against the previous can fillers. The can fillers will
hold the vertical on center line.
Apply a bead of sealant to the
receiving race for the can filler prior
to installing the filler. Fill this cavity
completely to ensure an adequate
seal. Clean off any excess.
Set the sill and head receptor can with 1/4" diameter minimum fasteners,
4" from jambs and verticals and then 16" on centers.
Seal over all fasteners (typ.).
If end caps are being incorporated,
install them now with sealant at the
ends of the receptor can.
