Bolt Through
This is the most common and probably also the most secure method of fixing. The handle is bolted through from the other side of the door with a flanged head bolt, usually with an M8 thread. This means that the bolt heads are visible on the other side of the door – these are normally then covered over with a push plate.
Secret Fix
Secret fixing does not use a bolt right through the door and therefore is not as strong a fixing as the bolt through method. Instead a stud is face fixed to the door with a wood screw and the pull handle legs are grub screwed onto a groove in the side of the stud. This can be a useful fixing to employ when you can’t use a push plate on the other side of the door.
Rose Fixing
This is another way of front fixing which is stronger than the secret fix outlined above but however does not look so elegant! A base rose, usually around 50mm diameter, is mounted to the pull handle legs. This is then screwed to the face of the door with up to 4 fixings screws per rose. The screws are then concealed by a rose cover.
Back To Back
When mounting a pull handle to both sides of a door, back to back fixing is employed. The fixing is similar to a ‘secret fix’ with one handle grub screwed onto a stud. However instead of a screw holding on the stud to the door, it is secured by the bolt through bolts of the pull handle on the other side of the door. This is a strong fixing and can be utilised on glass doors with the addition of nylon bushes. Nowadays some manufacturers sell a retro fit conversion kit that converts standard pull handles for back to back use – be aware that these kits are not as strong as the traditional method described above! We do not use them unless specifically requested to.
