 LADDER AND TRAY COVERS
Covers are normally specified where protecton is required:
1. To safeguard against damage to cable and insulation from falling objects—dropped tools, discarded cigarettes, sparks or solid materials.
2. Covers protect cable insulation and fixings (plastic ties etc.) from harmful effects of ultra-violet light or weathering deterioration.
3. In areas where high levels of airborne particles are present, covers prevent accumulation of dust or other debris on cables, which may cause heat build up, fire hazards or absorb moisture, which may shorten life of installation.
AVAILABILITY
Standard covers are available for all Unistrut® cable ladder systems and UNI-TRAY® systems. Standard length is 3 meters. Flat, peaked or ventilated covers are available by special order.
MATERIAL
Hot-dip galvanised steel sheet to AS1397.
STEEL STANDARD COVERS
    W
STANDARD COVERS
The most common type used. The 3-5° crease allows for maximum protection to cables. The standard cover has a 3-5° crease for added rigidity and mositure run-off.
       W
   FLAT COVERS
Most commonly used where there is space restrictions and the use of standard and peaked covers is not practical.

     VENTILATED COVERS
Should be used wherever reasonable protection for cables is required and where there is also a primary requirement to allow the escape of heat generated by cable.
SPECIAL ORDER STYLES
OTHER FINISHES
Also available in 316 Stainless Steel as a special order. Part Number example LU....3
Stainless steel part numbers are similar to the Hot dipped galvanised part numbers, but replacing the second letter of each part number with “U” and removing the H.
    W
PEAKED COVERS
Used in very dusty situations where the self cleaning effect of slopping sides prevents excessive dust accumulations. The large air-space above the cables also assists with the dissipation of heat.
