Overview
YOCL ELECTRIC MB Cable Marker Boxes hold the identification area within a covered box. The nylon construction includes a closing cover that helps shield the marker, providing a separate box format for wire and cable identification.
The series includes MB-3010, MB-3020, MB-4010 and MB-4020. Each model has its own dimensional combination. Select the complete model using the L, W, L1, W1 and B values in the table.

Technical Specifications
Dimension
Use the five dimension labels together when comparing models. L, W, L1, W1 and B retain the same notation as the dimensional drawing, with every value in millimetres. Select a complete model row rather than combining dimensions from different boxes.

Selection Guide
Compare the dimensional combination with the available identification space and the intended marker layout. Include all relevant dimensions where a box must match an existing arrangement. Keep the closing-cover format in the specification so the identification area is enclosed.
