Overview
Weighing 56 pounds with an 11 by 10 inch footprint, the Yost 910-AS is a heavy cast clamp meant for a fixed spot on a workbench rather than portable use. That mass points to a shop fixture built to stay put under load. It suits a dedicated station where the tool can be bolted down and left in place.
Yost has built vises and clamps for decades, and the 910-AS carries that heritage in its sheer bulk. Amazon's listing does not spell out jaw opening or throat depth, so buyers should confirm those figures against their own workpieces before ordering. What is clear from the data is a tool sized for permanent mounting, not portable clamping.
- 56 pound cast construction
- 11 x 10 inch footprint
- Built by Yost, a long-running vise and clamp maker
- Suited to permanent workbench mounting
Who it's for
Fits woodworkers or metalworkers setting up a fixed workbench station where a substantial, non-portable clamp earns its keep. Not a match for anyone who needs to move clamping power between job sites or store gear in a small shop.
Strengths and trade-offs
Drawn from this product's published specifications.
- Heavy cast build resists movement under load
- From a manufacturer with a long vise-making history
- No published jaw opening or throat depth
- 56 pound weight rules out portable use
- No seller description or listed reviews to confirm real-world fit
Performance notes
At 56 pounds and an 11 by 10 inch footprint, the 910-AS relies on mass and a cast body to resist racking under clamping pressure, the same principle behind Yost's vise line. Because Amazon's spec sheet does not list jaw opening, throat depth, or clamping force, buyers working with wide stock should verify dimensions directly rather than assume general purpose sizing.
