Track & Spring Preparation

NOTE:
Jambs, head framing and spring pads are not furnished by manufacturer.
Jambs must be flush and level around the entire opening and not have any fasteners past the face of the framing material. The jamb must be continuous and flush.

A.	Spring pad location (1 or more) depends on door size and number of springs used. Contact factory for exact location. If pad is wood, use #2 or better southern yellow pine. Do not use wood labeled SPF.
B.	Minimum 2" x 6" jamb facing or 2-1/2" x 3/16" steel channel should be securely fastened to the building structure.
C.	Opening width is determined by jamb to jamb (not including stop molding).
D.	Opening height is determined by floor to bottom of header (not including stop molding).
E.	Verify required door sideroom for hardware.
F.	Verify required door headroom.

Track & Spring Mounting

Reverse Angle
Primarily used on steel and masonry jambs, but may be used on wood jambs or optional wood covered masonry jambs. The door will overlap 1" on both sides and will close and seal up against the optional vinyl molding. Thus door needs to be 2" wider than rough opening width.

Bracket Mount
Used exclusively for wood or wood covered masonry jambs. Doors will close and seal up against the wood or vinyl stop molding. Door size equals rough opening. Stop molding will reduce the true opening width by about 1".

Continuous Angle
Used on larger doors on wood or wood covered masonry jambs. Doors will close and seal up against the wood or vinyl stop molding. Door size equals rough opening. Stop molding will reduce the true opening width by about 1".
