Rated 4 out of 5 by from Cost effective solution to Fire officer issue I have used several of these in my property. They save you having to hardwire your fire alarm to each firedoor to activate in the event of a fire.

Rated 5 out of 5 by from Fire Door Hold Open Retainer The feedback that I have received from our engineers is that this is brilliant - fitting instructions a little vague, but works brilliant when installed.

Rated 5 out of 5 by from Original and the best I have fitted loads of these. They are dead simple to fit and are a really easy way of getting over the problem of wedging open fire doors. My customers have always been happy with them too (care homes/schools/offices). The new ones on the market just don't have the reliability or simplicity. I would not risk it, just stick with what works!

Rated 4 out of 5 by from Good Product Good product, easy to fit, had a few issues with some not holding charge for very long as kept on beeping even though had put new batteries in. Other than that good product as does what it is supposed to do.
