PlasCity manufactures the PVC H Bayonet, an H shaped extruded profile used inside the Invisible Flange Joint to lock adjoining edges of PI insulation ducting panels together for a tight, stable seal during assembly.
What is an H bayonet
It is an edge locking insert shaped like the letter H, fitted inside the invisible flange joint to grip and hold two panel edges together at the joint line.
It keeps the panels aligned and locked in place inside the flange joint, preventing edge slippage or gaps opening up over time.
What to check before selecting one
- Snug interlock grip inside the flange joint that holds both panel edges without loosening under vibration or handling
- Consistent H channel depth so it fits panel thickness evenly along the full length
- Correct sizing to seat properly inside the invisible flange joint it will be paired with
- Enough rigidity to keep panels aligned without bowing or twisting
- No brittleness or cracking when panels are slid into the channel during installation
- Supplier can match the H channel width to both your panel thickness and your flange joint profile
