Belt Splices - Metal

These are exceptionally strong metal splices. Metal lacing / clips are meshed together and, in some cases, joined by inserting a metal pin. This provides a flexible splice and enables the belt to be installed without taking the machine apart.

Clipper Splice

Metal Hook - 'Clipper'

Individual metal hooks, sometimes referred to as 'clips' are held on a card (typically 12 in. long) and installed in the ends of the belt by a special press. The card is then removed. This type of splice is often called a 'Clipper®' joint.


Because of the thinness of most Green Belting materials the belt end must be reinforced for most types of hinged fasteners. The reinforcement for metal hooks and lacing is relatively heavy and is known as 'bullnose'.



K2SP (Biscor Code)
Wire dia: 0.62mm
Pitch: 1.70mm (59 hooks/100mm)
Produces a flat unobtrusive splice generally used on belts up to 1500mm wide
Temperature rating: - 50° to + 260°C

The finer wired K2SP (Biscor product code) has a greater total cross section of wire than the coarser K4SP and all things being equal should be stronger. However, abrasion of the splice and perforation of the bullnose must also be taken into consideration. The effect of these varies with type of material. Available normally in Galvanised Steel or Stainless Steel.

Wire dia: 0.80mm
Pitch: 2.54mm (40hooks/100mm)
Temperature rating: - 50°C to + 260°C
Similar to K2SP but produces a splice which can be easier to install on wider belts because of its greater pitch. Only available in Stainless Steel

Wire dia: 1mm
Pitch: 3.175mm (32hooks/100mm)
Temperature rating: - 50°C to + 260°C
The SW001 splice is similar to the K2SP and K2SP except that the hooks are held together by a welded wire, which remains attached after installation.


Metal Lacing -  'Alligator'
This type is often referred to as 'alligator'. The stated advantage is that as the fastener is produced from continuous strips of pressed metal, there is little danger of pieces of metal becoming detached from the belt into the medium carried (which may be food). This can be a problem with carded hooks but can also happen to lacing when abrasion is severe. A disadvantage is that metal lacing damages the 'bullnose' on installation and this can lead to premature failure. Also, if damage occurs at the side of the splice and because the lacing is in one piece, all of the lacing can work loose, something that does not happen with carded hooks as only individual hooks are lost and not the complete splice. Our policy is to generally recommend hook rather than metal lacing fasteners, except for food applications.

Metal Spiral

Metal Inox Spiral Splice
Wire dia: 0.70mm
Stainless Steel spiral woven into Aramid mesh material produces a flat, flexible and breathable splice.
Temperature rating: - 50°C to + 260°C
