Hydraulic-oil-leak-transom-door-closer-installation-400Hydraulic door closers are all designed with a spring which allows the door to close.

They are all equipped with a piston with a hydraulic seal which moves along the cylinder.

A valve which opens and closes is positioned at the top of the cylinder.

The door closes slowly and quietly when the valve is closed off because the hydraulic fluid is pushed slowly into the reservoir.

However, as the valve is opened, the fluid is pushed into the reservoir faster thus allowing the door to close quickly.

A simple adjustment of the valves on the door closer allows us to manipulate the rate and speed at which the door closes. This can be adjusted to suit individual preferences.

Why you need an expert for installations and repairs

Most door closers have two or more valve adjustments. One valve adjustment operates to regulate the closing speed of the door. The other valve adjustment facilitates the latching speed of the door. The speed of the door closer is in general, between 100 and 20 degrees, whereas the latching speed operates between 20 and 0 degrees. What confuses inexperience handymen is that, in addition to these valve adjustments, door closers have other similar adjustments which can be mistaken for valve adjustments. Any mistakes here can significantly damage your door. have expert technicians, fully trained in all door closer adjustments to avoid common mistakes during repairs and installation.

Surface Mounted Door Closers are visible on the door or frame.

However, some are located in the floor or in the top door frame itself – these are called Transom Door Closers. The ones which are installed in the floor are called Floor Spring Door Closers.

Surface Mounted Door Closers

Surface Mounted Door Closers are usually installed on the inside of an inward opening door and their arms project at right angles to the face of the door.

Those Surface Mounted door Closers found on the inside of an outward opening door have arms running parallel to the face of the door.

Crucial differences you need to know about

There are important differences in methods of installation which are crucial to the correct operation of the door closers.

It is important for the door closers to be installed at the designated height, relative to the door frame. Also, it must be installed at the designated distance from the door jamb.

These specifications for installation are determined by the manufacturer so that the door closer operates effectively and therefore, has a longer life.

In the case of hidden door closers, there are no hinges on the door and door jamb.

However, in the case of a floor spring, there is a pivot at the top of the door going into the transom door jamb. On a Transom Door Closer, the pivot bearing is on the floor.

Transom Door Closers

These door closers can be identified by a 40mm x 15mm plate which can be found at inside of the door at the top.

The plate is affixed to the door by two small screws – probably Phillips head. If the plate is absent – there will be two or three Alan screws. You can look for a brand name on the small plate if it is there.

Floor Spring Door Closers

This type of closer can be identified by another plate, usually found on the step underneath the door. The size of that particular plate can vary from 75-100 mm wide to 200-300 mm long and is usually shiny, stainless steel with a brand name. This metal plate is screwed to the floor spring with about four countersunk screws.
