System 28 Flex Stop 50 × 140 mm
The System 28 Flex Stop 50 × 140 mm is an adjustable positioning stop designed for D28 / Ø28 mm welding tables. Its elongated slot provides flexible positioning over a 100 mm adjustment range, while the rounded clamping surfaces make it suitable for corners, irregular workpieces, and free-form stop applications.
Compared with the 25 × 140 mm version, this model has a 50 mm material thickness, giving it a stronger and more substantial clamping surface.

Product Description
The System 28 Flex Stop can be individually adjusted through the elongated opening, allowing the operator to position the stop exactly where required instead of being limited to the welding table's fixed hole grid.
Its rounded contact surfaces make it suitable for use on straight edges, corners, curved components, and irregular workpieces.
The 50 mm thick design provides increased support and makes this version suitable for applications requiring a larger positioning surface.
A long clamping bolt is required for mounting.
Applications
Workpiece positioning
Corner positioning
Stainless steel fabrication
Curved and irregular components
Welding fixture construction
Profile and frame fabrication
Confined-space fixture setups
Repetitive welding and assembly
