Air System Equipment .'d^bSES?4 Duro-Dyne Corporation 800 Third Avenue, New Hyde Park, N. Y, Manufacturers of Accessories for the Sheet Metal, Heating, Air-Conditioning and Ventilating Fields DURO BLADE KIT Precision-built hardware for assembling multi-blade dampers. Reduces damper assembly time because of the uniformity of parts and the full adjustability which the kit provides. Damper blades are self-aligning, eliminating costly aligning procedures. Permits smooth, non-binding operation of dampers, even when a bracket is misplaced as much as 34 in. Blade openings are individually adjustable; correct clearance between blade and damper is automatically provided. Ap proved for use on dampers for the major control manufac turers. Air turning vanes made, with Duro-Vane-Rail save 50 per cent to 70 per cent in installed costs. Layout, drilling and riveting are eliminated. Vanes are sheared from scrap. No tab cutting on vanes is necessary. One blow on a chisel (supplied wito each bundle of Duro-Vane-Rail) securely locks vanes to rail. Duro-Vane-Kan allows maximum free area; eliminates noise and "whistle." Completed assembly meets most engineering specifications. DURO-METAL-FAB Flexible duct connectors for stopping travel of vibration noises are made up to three times faster when fabricated from preassembled Duro-Metal-FabMetal strips are already attached to fabric, eliminating this costly, timeconsuming step in the shop. Abe Double-Loc Seam assures a tight, permanent connection between fabric ana metal. Metal is heavy gage high galvanized iron or aluminum. Fab-r* is UL-approved canvas; heavy, tight weave asbestos or Neoprened Fiberglas. Supplied in continuous rolls containing 100 feet. 1450 Duro-Dyne Corporation Air System Equipment DAMPER REGULATORS AND CONTROLS (Formerly Manufactured by Parker-Kalon) UNXLD DAMPER QUADRANT SET-- % in. size used for dampers up to 20 in.; % in. size for dampers up to 30 in.
