Overview
The Rizom RZ9999 is an 11.8 inch wrench with a listed jaw capacity of 1.38 inches, a combination typical of an adjustable wrench sized for larger nuts and pipe fittings.
At 1.5 pounds it is lighter than a similarly long fixed-jaw wrench would be, which fits an adjustable-jaw design rather than solid forged steel throughout. No further material or finish details are given.

Who it's for
Fits users needing one wrench that spans a range of fastener sizes up to about 1.38 inches, such as plumbing or general repair work. Not the best pick for one repeated bolt size.
Pros and cons
- Wide 1.38 inch jaw capacity
- Long 11.8 inch handle for leverage
- Lighter at 1.5 pounds
- Jaw type, open end versus adjustable, not explicitly confirmed
Performance notes
The 1.38 inch jaw capacity sets the largest fastener this wrench can grip, and the 11.8 inch handle length adds leverage for loosening stuck nuts compared with shorter wrenches.
