Adjustable Leg for Modular Workbench

A modular workbench is only modular if every component scales the same way. The Unior 990LA-US Adjustable Leg is the bench-frame component that lets a shop build a non-standard bench size or correct for a non-level floor; an adjustable-height leg that attaches to any 2600-series bench top and lets the install fine-tune working height to the mechanic and the floor.

How it works

The 990LA-US is a leg, not a complete bench frame. It threads into the bench-frame underside at the standard mounting point and adjusts via the threaded foot for fine height-tuning. The adjustment range covers small (millimeter-scale) corrections for floor unevenness and larger (centimeter-scale) corrections for working-height preference.

When to specify

Three install scenarios where the adjustable leg is the right fix:

1. Non-level floor. The bench top sits true on a flat floor; on a service-shop floor pitched toward a drain, the bench drifts off-true. The adjustable leg corrects per-corner without re-pouring the floor.
2. Short-mechanic primary bench. For mechanics shorter than 5’6”, the European standard 91 cm bench top runs slightly tall. The adjustable leg lets the install drop the working height a few centimeters to match.
3. Custom modular configuration. A shop building a non-standard bench (combining a 990TW wood top with a 990WD7 cabinet at a working height that doesn’t match a stock 2600-series bench) uses the 990LA-US to set the floor height.

For tall-mechanic shops that need to raise the bench rather than tune it, the Cabinet Risers 990WDU are the dedicated 60 mm raise component.

Specs

• Type: adjustable-height bench leg.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The 990LA-US is part of the modular bench system; same manufacturing chain as the bench tops and cabinets it supports.

Pro tip from our mechanics

Adjustable legs are an install-time decision, not a retrofit. Specify them at order time if the floor is known-uneven or the mechanic working the bench is shorter than average. Retrofitting adjustable legs onto a bench already loaded with cabinets and tools means tearing the bench down first.
