What this is
A bar-clamp fixture that mounts onto a standard 2x4 you supply, rather than shipping with its own bar or needing 3/4" pipe like the fixtures in our pipe clamps comparison. The pitch is job-site practicality: instead of carrying dedicated bar clamps or a pipe-clamp fixture plus pipe, you grab a scrap 2x4 and turn it into a clamp on the spot.

Stanley STHT83166 2" x 4" Bar Clamp (2-piece set)
A different approach to the bring-your-own-bar concept than a pipe clamp fixture — this uses standard 2x4 dimensional lumber instead of 3/4" black pipe, which may be easier to source on a job site.
View Price on AmazonWho this is for
Job-site or on-the-go work where carrying dedicated bar clamps (or even a pipe-clamp fixture plus pipe) isn’t practical, but scrap 2x4 lumber is easy to find — and where bolting the fixture down for the 850 lb rating matters more than a lighter unbolted setup.
Who this isn’t for
Shop use where you already have dedicated bar, parallel, or pipe clamps on hand — a purpose-built clamp is generally faster to set up than mounting hardware onto a fresh piece of lumber each time. See our pipe clamps comparison if you’d rather standardize on one bring-your-own-bar system using pipe instead of dimensional lumber.
Bottom line
Multiple independent retailers agree on the core specs, but this is still a cross-referenced spec writeup, not a hands-on test. On paper the standout feature is real flexibility — turn any scrap 2x4 into a clamp, with a genuine force jump (400 to 850 lb) when bolted down. Stanley STHT83166 if job-site flexibility matters more than a dedicated fixture.
