Tools and equipment within this group are used to apply pressure and support during the stages of manufacture and assembly. The terms 'cramp' and 'clamp' are frequently used to describe these tools. Either term is acceptable. They are used to hold work to jigs or for gluing operations in furniture manufacture and assembly.


[edit] G Cramp

The 'G' Cramp with its heavy sectioned body, is suited to both cabinet and machinery work as vibration does not effect its holding ability. Available 'open jaw' range is from 65 to 300 mm ( 2 ½” – 12” ).

[edit] Quick Action Cramp

A very useful cramping medium for all woodworkers. The serrated edges of the bar ensures secure holding, however, they may prove unsuitable in vibrating situations. The size range of Jaw opening 'is 150 to 1000mm (6” – 3’), the smaller being of lighter construction.

[edit] Sash Cramps

The purpose of these is to apply greater pressure over a longer length. The variety of construction reflect their intended use on cramping timber, i.e. light or heavy pressure

[edit] 'T' Bar Heavy Duty Cramp

The heavy steel or aluminium bar and the coarse thread of the cramping mechanism are capable of applying tremendous pressure. Common capacity range is 600 to 1800 mm (2’ – 6’).

[edit] 'T’ Bar Lightweight Cramp

Intended for lighter use than the previous cramp, is also "available in aluminium or steel. Common sizes range from 600 to 1000mm ( 2’ – 3’3” ).

[edit] Rectangular Bar Cramp

Useful For light cramping only, is available from 500 to 1600mm (1’ 7” – 6’3” ) long in both heavy and light profile

[edit] Cramp Heads

These metal fittings are made to fit neatly over a 25 mm thick timber. Since these are interchangeable on timbers, cramps of any length are possible. Similar cramp heads are manufactured to fit 25 mm water pipe commonly known as Pipe Cramps .The handle end screws onto the threaded pipe. The other end contains a toothed cam, which grips the pipe. Pipes with threaded ends may be joined together with pipe jointers to create unlimited lengths.

[edit] Pipe Clamps

Similar cramp heads are manufactured to fit 25 mm water pipe commonly known as Pipe Cramps. The handle end screws onto the threaded pipe. The other end contains a toothed cam, which grips the pipe. Pipes with threaded ends may be joined together with pipe jointers to create unlimited lengths.

[edit] Edge Clamp

Edge cramps capable of grasping a panel between two jaws and also applying side pressure. This is very useful for the gluing of timber edge strips.

[edit] Corner or Mitre Cramps

Corner cramps also referred to as mitre cramps provide automatic cramping of mitres to form 90 degrees. Shaped profile moulds may provide cramping difficulties.

[edit] Webb Cramp

A webbing cramp consists of a webbing or polypropylene strap with a tensioning device that is usually tightened with a screwdriver. It is very adaptable for complex gluing tasks such as chairs, stools and picture Frames. The webbing also reduces the possibility of bruising the timber.

[edit] Flooring Cramp

This cramp is designed for closing up floorboards before nailing. Spring loaded cams give positive grip on joists. Easily portable with bevel gears for smooth operation.
