Duct Stretchers

Model DS3 locking duct stretcher pulls duct sections

together and holds them in place while freeing both

hands to align and install drive cleats.

Use the Duct Stretcher to hold duct in place

with one hand while slipping drive cleat in

place with other hand. The low profile, straight

body is designed to go anywhere, even in

the tightest quarters. Additional spacing holes

allow wheels to be adjusted to span greater

distances. Rugged anodized aluminum body

features large vinyl cushion grip and handy

hang-up hole.

knuckle contact with metal.

The DS3 locks on from either side of duct connection. No need to adjust wheels!

Simply place wheel located on moveable cam to one side of adjoining duct flanges.

Turn handle downward to pull duct sections together and lock in place. Greater

wheel clearance makes capturing the ends of duct sections, even misshapen flanges,

easier than ever. The versatile shape of the DS3 frame also lets you hook and pull duct

from above as the drive cleat is coaxed along the remainder of flanged track. The

durable all steel frame extends beyond wheel edges, making it safe to push, hammer

and bend drive cleats as necessary to complete installation. An offset handle design

eliminates knuckle contact with work.

Locks on from either
