tightest quarters. Additional spacing holes

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.
