What this is
A vertical-handle version of Bessey’s auto-adjust toggle clamp mechanism — the same self-adjusting principle as the STC-HH70 already on the site, but the handle swings down from above instead of across horizontally. That orientation difference matters on jigs where a horizontal handle’s swing path would hit a fence, wall, or another fixture.

Bessey STC-VH50 Vertical Auto-Adjust Toggle Clamp
Same auto-adjust mechanism as the STC-HH70 already on the site, but with a vertical handle swing — for jig layouts where a horizontal handle would hit an obstruction.
View Price on AmazonWho this is for
Jigs and fixtures where the clamp needs to sit close to a fence, wall, or adjacent fixture that a horizontal-swinging handle would collide with — the vertical swing path clears that obstruction.
Who this isn’t for
If your jig layout has open clearance and no orientation constraint, the horizontal STC-HH70 covers more holding capacity (700 lb max, same as this model) with a handle that’s arguably easier to reach across a flat table.
Bottom line
Two independent retailers agree on the core specs, but this is still a cross-referenced spec writeup, not a hands-on test. On paper this is the same reliable auto-adjust mechanism as the STC-HH70, just in a vertical-handle orientation for tighter jig layouts. Bessey STC-VH50 if a horizontal handle won’t clear your jig’s layout.
