Track/Rollers:
Track formed from strong galvanized steel, paired with durable, long-wearing steel rollers ensures smooth, quiet operation.

Insulation:
An energy-saving core of polystyrene insulation provides added comfort and helps keep your garage quieter. Shown at left with insulation core and without.

Section Joints:
Sturdy, roll-formed tongue-and-groove meeting rails seal out wind, rain, and snow, keeping your garage dry and secure.

Exterior Texture:
Authentic wood grain texture on the door's exterior adds visual appeal.

Tamper Proof Cable Attachment:
The tamper-resistant counter-balance cable attachment cannot be released while the cable is under tension, helping prevent injuries or accidents.
