Dayton 4ZW25 Beam Clamp
The Dayton 4ZW25 is a steel beam lifting clamp rated for a 10000 lb working load limit. It fits flat beam flanges from 3 1/8 in to 12 5/8 in wide and up to 1 1/8 in thick. Jaw opening ranges from 2 3/4 in minimum to 14 1/8 in maximum. Overall dimensions are 12 3/4 in high, 4 3/8 in deep and 19 1/4 in wide with a shaft attachment.
Suited for vertical lifts on structural steel
Riggers and maintenance crews who need a secure top-mount grip on standard I-beams will find the clamp matches the stated flange range. Operations requiring a larger throat depth, a different attachment style or a higher working load limit should evaluate other clamp types. The fixed shaft attachment does not swivel, so side-loading scenarios are not appropriate.
Steel construction holds rated capacity under
The clamp maintains its 10000 lb limit during sustained lifts without deformation when applied within the specified beam width and thickness range. Repeated cycles do not change the jaw geometry or reduce the grip on compatible flat flanges. Regular inspection of the contact surfaces and shaft ensures consistent behaviour over the service life.

Questions about this item
What beam width range must the structure fall within for the 4ZW25 clamp to fit?
The clamp accepts flat beams from 3 1/8 in to 12 5/8 in wide.
Will the clamp grip a beam flange thicker than 1 1/8 in?
No, the maximum beam thickness is 1 1/8 in; thicker flanges exceed the jaw capacity.
How can I confirm the clamp is seated correctly after installation?
Verify the shaft attachment is fully engaged and the jaws sit flush on the beam flange within the 2 3/4 in to 14 1/8 in opening range.
