Chamberlain 1703REV Arm for Canopy Doors, Grey, 11.5 cm*78.0 cm*21.5 cm

Already had a Door Motor but it would not work with the counterweighted Canopy Door. Decided to take a chance and get one of theses to see if the 'conversion' would enable me to automate the door.Thoroughly recommend for anyone wanting to electrify their Canopy door - but do make sure you have a fairly powerful motor as it requires quite a lot of effort to work the arm. On my full height single garage door works like a charm.Took about 40 mins to install on the door and 10 more to hook up to the Motor and set movement limits... Job done in an hour.Brilliant.

Installed a Chamberlain ML1000EVGB garage door opener to replace an old one. However, would not work with my canopy door & would just lock up. However, this canopy device solved the problem and works perfectly and now, the garage door opens nice & smoothly.

You will need this if you are using the Chamerlain up and over garage door kit for a Canopy Door - its a must. I did not receive any fitting instructions but I did find some on-line. In my humble oppinion they were about as usfull as a brick on the Titanic. Only the fact that I am a retired engineer saved me from pulling all my hair out, but in fairness I eventually worked out how to assemble it to the door. It worked like a dream - so it was worth the effort.The arm itself is well recommended and would have been given 5 stars if the instructions had been up to scratch.

Found this easier to fit than I first thought. It is very bulky though and hangs down a fair way below the door reducing clearance to below 6ft on my door so my next car won't be a tall one.

If you go for the 'option' of fitting the safety beam that stops your kids/pets getting squashed, you will be working from 4 separate instruction sheets. These are written by someone who doesn't have a good command of the English language. Thus, you will be struggling to understand what the hell you are being told to do. These days, a lot of products are sold with text-free instructions and convey all the information with careful drawings. Not so with Chamberlain door openers and their accessories. The drawings are way too small but carry vital information (the colour coding for the electrical connection being just one example) and with a very small font size in the text which doesn't help. I got there eventually but the whole fitting experience was and extended ordeal that took about 3 times as long as it should have done.

I wondered why I need this addition to the canopy door but it is essential and does a good job.The downside is that if you have one of these butch looking modern cars, there may not be enough headroom within 1.5m of the door as it opens. I have a Peugeot 3008 and there is an interference between raised tailgate and Chamberlain Arm if the car is less than 700mm inside the garage.However, as stated, if one of these arms is recommended, you DO need it.

Ordered this for my mom, who had it fitted by a local handyman. Think it took him about half a day, however it does what it is supposed to and mom is very please with it in her maturing years. The same product on the High Street is considerably more expensive.

Without the arm the up and over garage door would not have opened. The instructions are ambiguous at best but once configured correctly the door opens and closes efficiently .
