Overview
The BESSEY IBEAM36 is a bar clamp built around a steel I-beam, with an overall length near 42 inches and jaws around 4 by 2 inches. At 9.3 pounds it carries the heft typical of clamps meant for wide glue-ups rather than light hobby work.
BESSEY built its reputation on I-beam clamps for woodworking and metal fabrication, and the IBEAM36 name lines up with the 42 inch overall length listed, pointing to a long-reach bar suited to wide panel glue-ups or door frame assembly. The steel I-beam design is what gives it the 9.3 pound heft, more rigidity than a lighter aluminum bar but more weight to manage on a clamp rack.
- Steel I-beam bar construction
- Approximately 42 x 4 x 2 inch footprint
- 9.3 pound item weight
- 4.6 star rating from 152 reviews
Who it's for
This suits woodworkers and metalworkers who need a long clamp for wide assemblies, cabinet doors, or panel glue-ups rather than small joinery. It is not the choice for someone who only needs a quick spring clamp for light, short-reach holding.
Strengths and trade-offs
Drawn from this product's published specifications.
- I-beam bar resists twisting under load
- Long reach suits wide panel glue-ups
- 4.6 rating across 152 reviews
- 9.3 pounds is heavy for one hand
- Not suited to small, quick clamping jobs
Performance notes
An I-beam bar resists the twisting that flat-bar clamps can suffer under heavy clamping pressure, which is the main reason woodworkers reach for this style over cheaper alternatives. The tradeoff is the steel itself: at 9.3 pounds this is a clamp to plan storage and handling around, not one to grab one-handed for a quick tack.
