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: Bit stiff opening but stops door slamming - Bought this for the connecting fire door between our Garage and the kitchen. Which always slammed shut if not held. Fitting instructions to be honest could do with improving, as you can see from the downloadable version top of this page. Adjusting the tension was the reverse of what i am used to, usually i expect that turning a screw anti clockwise would take off the tension but its the reverse. Turn clockwise and the door slows down considerably. I would have given it 5 stars except for the instructions. But would otherwise recommend, good value for money. ## 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 | 179,122 in DIY & Tools ( See Top 100 in DIY & Tools ) 124 in Door Closers | | Brand | Briton | | Colour | Silver | | Customer Reviews | 4.3 out of 5 stars 258 Reviews | | Exterior Finish | Silver | | Exterior finish | Silver | | Global Trade Identification Number | 05050640018434 | | Included Components | Door Closer | | Installation Type | Screw-In | | Installation type | Screw-In | | Item Type Name | Briton CE Door Closer: Fixed Size 3 For Fire Doors | | Item Weight | 1.6 Kilograms | | 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 | | Size | Fixed Size 3 | | 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 ![121CE.SES CE Closer: Fixed Size 3 for Fire Doors, Silver - Image 1](https://m.media-amazon.com/images/I/51kaeSFRd2L.jpg) ## Available Options This product comes in different **Color, Size** options. ## 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.

I looked at a YouTube video , this made choosing the correct installation method easier and it only took 10 minutes to install , absolutely brilliant in every regard.
