Product description

The Norlok Watson Slip-On Flange is a lighter version of the Medium Duty Watson, built for slip-on flange duct work. From Norlok Technology Inc. of Brantford, Ontario, it forms a Clinchlok joint — the upper tooling squeezes two plies between a punch and die, locking them together with no rivets, bolts, fasteners, heat or adhesives, no fumes, and little or no damage to painted or galvanized finishes.

Its single steel C-frame has a dual trigger with a toggle to close the height, an air-over-oil intensifier and an adjustable pressure-sensing return (24 vDC). With no consumables and clean operation, it is stainless capable and ideal for fastening easy-to-clean ductwork.
