GYM DIVIDER CURTAIN
	
	A. 	Model 4025 Slope-Fold: Electrically operated, fold-up gymnasium divider conforming to roof slope and including motor winch, cables, sheave assemblies, controls, clamps for attachment to building structure, supports, and other components required for complete functional installation; Ridge-Fold Gym Divider as manufactured by Performance Sports Systems.

		B.	Operation:  Gym divider shall utilize pivot joints to fold compactly into roof contour.  Curtain moves by accordion fold-up action as weighted bottom is raised by hoist lines passing through curtain grommets.  Hoist lines pass through sheave assemblies attached to roof structure.  Lines pass through intermediate sheaves which act as idler assemblies and direct lines to motorized winch.  Lines terminate at individual drums sized in variable ratios allowing raised curtain to conform to roof slope.

		C.	Configuration:  Pivot joints in top and bottom batten pipes allow divider to conform to roof contour in both open and stored positions.  Divider extends across room as indicated on Drawings.

			1.	Minimum required clearance between vertical curtain edges and adjacent fixed objects: 6 inches.

			2.	Provide 36 inch space between curtain ends and walls or fixed objects to allow passage space around divider.

		D.	Operating winch:  Powered with C-Face motor sized for specific project torque requirements and equipped with thermal overload protection and rotary counting limit switch to control curtain travel.  Individual drums sized in variable ratios shall be provided for factory termination of each cable.  Winch to be attached to roof structure.

		E.	Sheaves:  Heavy-duty assemblies with roller bearings and attached to roof structure at each hoist location.

		F.	Hoist lines:  1/8 inch diameter steel cable with 2,100 pounds minimum breaking strength.  Lines shall attach to battens concealed at curtain bottom, pass through curtain grommets at 18 inches to sheave assembly, continue through intermediate sheaves along slope of roof to winch, and terminate at individual drums.  Space lines at approximately 111inches. 

		G.	Top curtain support: 1-5/8 inches diameter steel pipes with pivot joints in curtain pocket and suspended from sheave assembly and roof structure with No. 2/0 chain.
