Buckley’s Buct Duct Triple Lock ducting is an all metal flexible duct that is constructed entirely without the use of adhesive. The Triple Lock mechanical joint makes an air-tight seam, while the circumferential corrugations provide excellent strength and flexibility. Triple Lock Aluminum ducting may be easily cut to size and hand formed into elbows or offsets to suit job conditions without subsequent sagging or droop. Triple Lock has much lower pressure loss than conventional cloth ducts due to small but consistent corrugations that provide both strength and flexibility.
