What this is
A 90° corner-clamp square with an aluminum die-cast body and chrome-plated steel screws, in the same general category as the Bessey WS-3+2K and Irwin 226200 in our corner clamps comparison. The distinguishing feature is a slotted base built for bolting the clamp down to a drill table or other fixed surface — useful if you want the clamp to stay put rather than being held or repositioned by hand.

Bora 551025 90-Degree Quick Release Corner Clamp
The slotted, boltable base is the standout feature versus other corner clamps on the site — useful for a fixed setup rather than hand-held repositioning.
View Price on AmazonWho this is for
Repeated small-assembly or picture-frame work where bolting the clamp to a drill table or dedicated jig surface saves you from re-securing it by hand every time.
Who this isn’t for
One-off or portable use where you don’t want to bolt anything down — the Bessey WS-3+2K and Irwin 226200 in our corner clamps comparison are simpler hand-held options without a mounting base.
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 the boltable slotted base — a fixed-mount option the other corner clamps on the site don’t have. Bora 551025 if a bolt-down base fits your setup.
