How KONOK Supports Your Project
Description
Our KONOK L-Shape Riser Block delivers high strength and reliable perpendicular stability for modular welding fixturing and right-angle positioning. Featuring 4 precision-machined working surfaces, it serves as a clamping tower, lateral stop and system connector, adding third-axis expansion without requiring a larger fixed welding table.
Key Features
- Available in sizes from 500×200×100mm up to 2000×200×100mm.
- Diagonal 100×100mm hole grid pattern supports flexible angled fixturing.
- Four-sided precision machined working faces with tight geometric tolerances.
- Assembles vertically as a clamping tower or horizontally as a lateral stop.
- Compact L-shaped design fits tight, confined working spaces.
- Fully compatible with D28 28mm metric series welding tables.
