Features
- Improved weather sealing and draught proofing performance from extended enclosed end cap and asymmetrical vent arm form when tested to BS 6375-1
- Lipped slider for enhanced smooth operation
- Easy friction adjustment without metal to metal contact
- Uniqure robust cam friction device eliminates any risk of friction screw misuse
- Slot-hole-slot vent fixing configuration for ease of adjustment and guaranteed fixing into reinforcement on PVC-u window frames
- Enclosed end cap to prevent ingress debris and provide increased cavity tolerance

- For austenitic variants add 'A' to end of part code (not including 6")
- For slimline variants add 'S' to end of part code (not including 6", 13mm stack height only)
- For timber variants add '-TV' to end of part code (13mm stack height only)
Note: As with all types of friction hinges, friction cannot be provided until the slider moves, therefore when opening top hung vents to angles of 10° or less a separate device may be required to prevent the window from closing.
