An escalator step pallet has step tread and front riser portions joined together with side edges. The side edges are provided with a peripheral slot to accept replaceable demarcation inserts which identifies the side edges. The slot on the step pallet is provided with guides extending along its length to accept channels of the demarcation inserts and orient the demarcation inserts on the step pallet. Preferably, a pair of demarcation inserts are provided for each step edge, the first insert extending along the step tread and the second insert extending along the riser. The two inserts may interlock. In addition, each of the inserts is provided with a locking device which mates with a corresponding element on the step pallet to retain the insert in position. The locking device may be for example, a hook arm which engages a projection on the bottom surface of the step pallet. An access slot is provided through the insert and pallet to permit a tool to contact the hook arm to release the lock when removal of the insert is desired.
