Motor and Switch

Motors are adapted with brake and free wheel clutch mechanisms to fight the forces of gravity and deliver protection to even the oddest shaped openings. The free wheel clutch and brake components actually allow the cord to lift the curtain away from the axle at the same rate the motor engages the cord pulley. All of these different operations are synchronized in order to make the system work properly. Torque limits are included in the motor that stops the shutter operation when faced with a blockage or obstruction. This eliminates damage and the need for costly service calls.


The housing is a preassembled, modular system. It is square 90° or 5 sided 45° in design and is enclosed (with the exception of the slat aperture) in a roll formed aluminum skin. Its finish consists of baked on polymer based enamel in colors matching the tracks. The front and lower portion of the housing is a detachable access panel. They are two piece coverings. The back covering is pop-riveted or screwed to the housing and fastened to the studs above the protected area. The front covering is attached to the housing with sheet metal screws and employs a track on the bottom to attach the storm bars, if storm bars are needed.

End Caps

The housing is supported at each end by die cast aluminum reel supports, which include stamped aluminum alignment plated and injection-molded nylon slat guides.

Tracks / Guide Rails

Side Tracks a.k.a. Guide Rails

Side tracks are extruded aluminum 6063-T5 with a baked enamel finish. The tracks undergo a five-step pre-treatment process prior to the electrostatic application of a high solid polyester based enamel. The finish is applied in accordance with AAMA Standard 603.8. All side tracks are lined internally with tightly woven polypropylene runners. The wall thickness is 0.06".

Split Rails / Storm bars

Split Rails are extruded aluminum 6063-T6. They are lined with polypropylene runners on the surface which contacts the slats. Spring loaded attaching mechanism and flush mount receptors are standard equipment.
The storm bars are constructed of 0.09" thick extruded aluminum channels with an aluminum key at the bottom and spring loaded aluminum key at the top. The storm bars utilize two rows of 0.15" high by 0.27" backed poly pile weather-strip. Different shaped storm bars besides the I-Beam are available.


Extruded Aluminum

1) Powder coated
2) Electro static finish


The Endslats have a solid double-wall extruded aluminum profile specifically designed for the Studio Star system.


Installation must be performed in accordance with local code requirements. All exposed assembly and attaching hardware is 18-8 non-magnetic stainless steel.

Color Selections

Upper housings, tracks and slats come in white, cream, light beige, brown and gray.
