Hinge Size Configuration:

Hinges are measured by its height and its width. The first dimension is the height and the second is the width. Width is measured provided that the hinge is in the open position as shown in the figure below

Determining the number of hinges needed: Generally there should be 1 hinge for every 30" of door height. Refer to table below for quick reference.

WIDTH = DT - HB × 2 + CR

DT - DOOR THICKNESS HB - HINGE BACKSET CR - CLEARANCE REQUIRED If the result of the formula above would correspond to a non standard hinge, then go to the next larger hinge width. RECOMMENDED HINGE BACKSET: For doors 2¼" thick and below, ¼" (6.4 mm) backset is recommended. For doors over 2¼", ⅜" (9.5 mm) backset is recommended. Selecting the Proper weight and Bearing Type: Standard Weight - Plain Bearing Standard Weight - Ball Bearing, Concealed bearing Heavy Weight - Ball Bearing, Concealed bearing Considerations in determining Weight and Bearing type: 1) Weight of Door 2) Frequency of Use 3) Frame 4) Door Hardware Always use ball bearing or concealed bearing hinges for doors with door closers and in all fire rated openings. Heavy Weight doors and high frequency doors should use heavy weight ball bearing or concealed bearing hinges. Use ball bearing or concealed bearing hinge with spring hinges.

Determining handing:

Some hinge applications require correct hinge handing. It is therefore necessary to distinguish what type of hinge handing a particular application may require. Shown in the illustration below, the suffix L.H. (left hand) and R.H. (right hand) would classify their handing.

The hand of a hinge is determined from the outside of the door to which it is applied. This is usually the locked side. When standing outside, if the door opens away to the right, it requires a right-hand hinge also referred to as RH. If it opens away to the left, then it requires a left-hand hinge also termed as LH. When standing outside, if the door opens towards the right, it requires a lefthand hinge, also referred to as right hand reverse bevel or RHRB. If it opens towards the left, it will require a right-hand hinge, also referred to as left hand reversed bevel or LHRB.

Types of Finishes:

All steel and brass material hinges can be plated to match the available finishes that are listed in the American National Standards Institute or ANSI, standard ANSI/BHMA A156.18 Materials and Finishes.

Anti-rust finishes:

When using steel based materials hinges, special finishing procedures can be done which will improve and add protection to the product. A nickel undercoat may be applied prior to plating. But although this will give added protection and make it rust resistant, it is still not considered rust proof. Stainless steel or brass which is a non-ferrous material may be used if a true rust-resisting hinge is needed.

Electrified Hinges:

The Electrified Hinge made door wiring easy, safe and reliable. Power can now be transferred from the frame into the door either exposed or concealed. With the introduction of electrified hinges, we are now able to monitor the position of the door, transfer power and incorporate both functions into a single hinge. More so, we now have the ability to electrify other hardware items such as exit devices, electric strikes and electrified locks. Full mortise hinges are highly recommended for modification purposes. However, monitoring can be supplied on a half surface hinge if the need arises. It is also recommended that the Center Hinge Location be used with all electrically modified hinges. The maximum voltage that is allowed in electrified hinges is 48 volts. Higher voltage is not allowed because of potential dangers. The current (amperes) should also be taken into consideration.

4, 6 and 8 wire available on all standard weight, heavy weight and concealed ball bearing hinges in all sizes. Specify Hinge.

Standard weight door receiving average frequency service (standard weight hinges) and high frequency service (heavy weight hinges). Designed to have both leaves mortised into the door and the jamb. The hinge sits flush with the surface of the door and frame.
