## Description

Chamberlain External Emergency Release 1702REV-01 - Mechanical Emergency Release - Easy Operation - Incl. 2 Keys & Mounting Hardware : desertcart.co.uk: DIY & Tools

Review: Good, but will rust on you so prepare it first. - For what these are, they are quite expensive. In saying that, it does the job well. The only downside is that after two years, my original one rusted solid so the barrel wouldn't turn. It isn't the best quality, but I do live about 100ft from the sea. When installing, I packed it full of molybdenum grease to stop this happening again. Remember, you won't be using this much so it may happen to you also. Another thing I had to do when installing was to pack out the back of my garage door with wooden blocks to give some reinforcement to the back of the door once the whole is cut, then pass the attaching screws through them. Overall, I bought another one so that should tell you it works and I am happy with it.
Review: Works as it should. - Reasonably easy to fit and works as it should.

## Questions & Answers

**Q: What is the diameter of the cylindrical section that goes through the door + length of cable?**
A: Cylinder diameter is 18mm ---L ength of cord is about 60". There's certainly plenty to spare on my garage door

**Q: Do you fit this to the wall or to the garage door?**
A: This fits to the garage door and connects to the door opener. When you put the key in the lock, the lock pulls out towards you - when the pull the lock all the way out it disengages the door opener mechanism from from garage door and you can open the door manually. 
The cord is long enough if the lock is fitted to the door, but it wouldn’t stretch to the wall, and works best when it is in line with the door opener mechanism.

### ⭐⭐⭐⭐ does the job
*by L***H on 6 March 2021*

A metal hole drill makes fitting a lot easier. It does what it should do. Key better than a lot of other spade type keys.
