Polyurethane side bars come in various sizes, the most common size of side bar supplied by SCS is a 50mm wide and 60mm high bar, the length is varied to suit the screen length but normally a maximum of 1250mm long. There are twenty different width and height combinations of side bar that SCS supplies as standard and other can be made on request.
Side bars typically constructed from a steel plate or steel hollow section for strength and then polyurethane is moulded around all sides with attention paid to the thickness on the wear faces of bar.
Other more specialised side bars are available most commonly for the 85 system which have profiles moulded to them or are knocked into the 85 system girder are also available.

Polyurethane Wedges and metal cleats are used in conjunction with polyurethane or polyethylene side bars to clamp down screen media at each side of the screen.
Polyurethane centre hold down bars are normally used in conjunction with the SCS plank system or polyurethane tensionable screen mats but are not limited to these two applications. Centre bars are essentially a bar which clamps something down most commonly in the centre of a screen. The SCS plank system has a centre bar with normally two or three holes in it that is used along with the pin and wedge clamping system to retain the centre of the module system, however this system can also be used on polyurethane tensionable mats or rubber screen cloths.
Another form of centre hold down is the bolt down version, which is when captive bolts are protruding up from the screen frame and the centre bar is used to bolt the screen media in place.
The SCS centre hold down is made from a steel channel section for strength and rigidity and then the wear resistant polyurethane is moulded around it to give the final product.

Slotted Pins, Metal Wedges, and Polyurethane Protection Caps work together to secure centre hold down bars over the Plank Modular System. The metal wedge is secured through the slotted pin with a hammer to lock the screen deck firmly in place. Strike the wedge in the against flow direction to release it and remove the centre bar. This allows two to four modules to be lifted out at once, thus improving maintenance efficiency and providing clear access to the deck below. Because the system uses a horizontal hammer strike, it suits screens with limited space in lower decks where vertical hammering is impractical or impossible.
Capping rubber is mostly commonly fitted on camber bars for support under tensionable screen media. Capping rubber is also known as bucker up bar rubber, nosing rubber and many other names. SCS stocks over 4000m of capping rubber in 20m rolls, it comes in three size type 0, 1 and 2. Type 0 has a 10mm lift (cap), Type 1 a 15mm lift and Type 2 a 20mm lift.
Polyurethane dam bars come in two sizes for the SCS plank system the most common size of dam bar is 30mm high and the other is 75mm high. The dam bar is designed in such a way that it sits down in the modular system between two modules and is held in place by the side and centre bars.
