Rated 5 out of 5 by from Good ternative to electromag Great alternative to electromag door holders. A bit pricey but much cheaper and quicker than installing electromags. I have installed these for years and rarely have any problems other than replacing batteries. Most often very easy to install, on rare cases the door might need shaving off slightly to fit the plate in the floor.

Rated 4 out of 5 by from Black Dorgard We use these on internal doors in a Care Home. They work better using the floor plate, especially if using on carpeted flooring. They serve a good purpose for us and the bulk buy price here is one of the best available I have found.

Rated 5 out of 5 by from Good bit of kit Easy install very reliable does need sensitivity adjusted as hoovers and kettles can set it off. All in all a good bit of kit.

How could this be used to hold a door open when the floor level on the open side is lower

Asked by: GeeBee42

Can this be activated by a smoke detector sound?

Asked by: GeeBee42
If the smoke detector siren emits a continuous sound that is at least 65db where the Dorgard is installed and emits continuously for 14 seconds then yes it would be activated. Anything giving a continuous sound above 65db operates it (drill, vacuum cleaner, loud music etc.)

If you had several of these devices would you have to reset them all after they were activated

Underfloor heating

Have underfloor heating and don’t want to drill in to the floor, the floor is carpet. Any advice on securing the floor plate?
Asked by: Bob6699
Depending on the closing force, you may not require a floor plate. Fire doors weighing more than 120kg, which have a closing force in excess of 120 Newton Metres (that’s a closing force of about 15kg, 800mm from the hinge) must have the Floorplate installed in combination with the Dorgard unit. Dorgard can hold a fire door open safely without the Floorplate installation if the fire door’s weight and closing force are less than those listed above.

Challenges fitting with concrete floors

Our floors are concrete and I don't fancy drilling 6 holes 40mm deep as per instructions to fit the floor plate. Can the Dorgard be effectively used WITHOUT the floor plate?
Asked by: ADavids
I have a door that requires a plate and a door that works fine without. It depends on the closing force of the self closing unit. Fire doors weighing more than 120kg, which have a closing force in excess of 120 Newton Metres (that’s a closing force of about 15kg, 800mm from the hinge) must have the Floorplate installed in combination with the Dorgard unit. Dorgard can hold a fire door open safely without the Floorplate installation if the fire door’s weight and closing force are less than those listed above.
