Summary
Welping HDPE stub end holders feature adjustable clamping positions and hand knobs for securing stub ends during butt fusion welding. Models from 160 to 2250 are available, with custom sizes and mounting configurations to suit specific requirements.
Welping HDPE stub end holders secure stub ends for butt fusion welding with a compatible fusion machine. Featuring a steel plate structure, adjustable clamping blocks and hand knobs, they allow operators to adjust both clamping position and tightness. Multiple models and custom sizes are available.
Adjustable Clamping Design
The clamping blocks slide along slots in the plate. By loosening the fixing bolts, operators can reposition the blocks to suit the stub end dimensions, then tighten the bolts to lock them in place.
The black hand knobs adjust clamping tightness to secure the stub end. Together, these adjustments help operators set up the holder for different stub end sizes within each model’s clamping range.
