Incorporates corrosion-resistant components to assure a smooth, controlled descent. Protected by a head plate cover.
A torsion-spring-operated system, enclosed in a structural steel barrel, effectively counterbalances the shutter for a minimum 7,500 cycles.
All curtains are constructed from heavy-duty, 22-gauge steel or stainless steel flat slats.
Curtain bottoms are constructed of tubular steel or stainless steel with closed-cell foam seal to protect the sill.
Guides and End Locks:
Guides are constructed of fabricated painted steel or stainless steel. Stamped steel end locks secure the curtain.
