Connectors & Fittings:

Necessary connectors and fasteners are supplied with all trays and fittings. Extra connectors for field cuts or spares must be ordered separately.

Safe Load:

Allowable cable load in pounds per linear foot uniformly distributed. Based on tray with standard rung on 9" centers and supported on simple beam with safety factor of 1.5 per NEMA VE1.

Concentrated Load:

All ladders with solid rungs and trays with corrugated bottoms will support a 200 lb. concentrated load applied at the center of the tray in addition to the NEMA -rated cable load without collapse (except NEMA Class 12A trays).

*Rail flange size determines which series connectors are needed. Please consult the chart above to determine the connectors you need.

SERIES 1

Fitting side rails have 2" tangents (flat portion beyond curvature) at the end of each fitting, to accommodate splice plates with four holes.

SERIES 2

Fitting side rails have 5" tangents at the end of each fitting, to accommodate splice plates with eight holes.
