Box Contains Overhead Door Closer, complete - with Fixings Review: Briton 121 is a first class device - Briton 121CE SES size 3 door closer: Bought this as previous door closer gave up after 28 years. This Briton model is heavy duty and you immediately notice the quality. There is a paper template which I attached by tape to the corner of the door and this indicates where to drill 4 holes. I used and B&D but you could use a hand tool. The top part of the device comes apart for ease of fitting and it is bolted to the top of the main unit. The top arm of the pivot is screwed to the door frame exactly 50mm from centre of the screw position on the main unit. The template shows you where this is screwed so simply study the template and follow it. The two halves of the pivoting bar are then cliked back together again and hey presto apart from fitting a plastic cap over the lower bolt of the cam the job is done. You can adjust the pressure of the cam but I found it was ok and its a brilliant piece of kit. Made such a difference Review: Nice product but instructions not clear - We fitted this to stop a door slamming in the wind...... The instructions took so time to work out and it didn't really state how to adjust the closing speed etc, but once fitted the product works well. We did fit it on a utility door and my wife has commented that its a but stiff to open, but I find it ok. Only down side is she now wants a door wedge so she can wedge it open as she gets fed up of it opening and closing...... "just no pleasing some people" :-) Quick update, we’ve now fitted magnetic door opener, which in conjunction with this closer works brilliantly.... we can now have it closing automatically or leave open if we are using the door a lot..... everyone’s happy now😁 ## Features - Overhead fixed power 3, CE Marked and Certifire approved - Fire tested to EN 1634 for 2 hour Timber Doors and 4 hour Steel Doors ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0036QYOAM | | Best Sellers Rank | 61,249 in DIY & Tools ( See Top 100 in DIY & Tools ) 46 in Door Closers | | Brand | Briton | | Colour | Silver | | Customer Reviews | 4.3 4.3 out of 5 stars (258) | | Exterior Finish | Silver | | Global Trade Identification Number | 05050640018434 | | Included Components | Door Closer | | Installation Type | Screw-In | | Item Type Name | Briton CE Door Closer: Fixed Size 3 For Fire Doors | | Item Weight | 1.6 Kilograms | | Manufacturer | Allegion | | Material | Metal | | Model Number | 121CE.SES | | Number of Pieces | 1 | | Part Number | 121CE.SES | | Recommended Uses For Product | closing fire doors | | Specification Met | CE, Certificate, EN 1634 | | Unit Count | 1.0 count | ## Product Details - **Brand:** Briton - **Colour:** Silver - **Exterior finish:** Silver - **Item weight:** 1.6 Kilograms - **Material:** Metal ## Images ![Briton 121CE.SES CE Closer: Fixed Size 3 for Fire Doors, Silver - Image 1](https://m.media-amazon.com/images/I/51kaeSFRd2L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Briton 121 is a first class device *by N***N on 12 December 2016* Briton 121CE SES size 3 door closer: Bought this as previous door closer gave up after 28 years.
