## Questions & Answers

**Q: Can this be adjusted for opening resistance?**
A: Opening resistance isn't adjustable. You can adjust the speed of closing, and the super-slow final closing cushion. Be aware this closer is better suited to a lightly trafficked door of relatively compact dimensions, despite what the sales blurb claims.

**Q: Can this be used on both inward and outward opening doors**
A: Dear Toni, thank you for your message.  These can be used on inward or outward opening doors.  Please do not hesitate to contact us for further information.  Kind regards JC Plastics Ltd

**Q: Will this stop a door from slamming, i.e. control its speed when it is closing?**
A: lol errrr YES that's what it was designed & made for! By the way - the sky IS blue - you're alright! ha ha ha

**Q: I have just installed this on a communal door.  Please explain what cam screw "1" controls and what cam screw "2" controls.  Not clear!**
A: One of the screws controls the speed of closer from 0 wide open to about 80 almost closed.
The other screw controls the other 20 to latch the door. 
Open or closed windows can also affect the latch by causing a vacuum in the room to the door in question.
