Drilling holes for cable tray bolts
Drill the drill holes with ∅ ≥ 7 mm in the tray rail and tray base. To avoid transverse bending at higher loads, a joint plate must be used for tray widths of 400 mm or more in the joint area of the cable trays that are to be connected. Structural building members should never be cut, and cable trays should not be installed in hoist way or where subject to physical. If unperforated cable trays are cut, then appropriate drill holes must be drilled for the straight connections and for the mounting of fittings and joint bars. Recommendation: For side height 60 mm = 4 screws per. In this video, watch the complete process of installing a cable tray on site — from climbing the ladder, drilling holes, fixing rawl bolts, tightening supports, and finally mounting the cable tray for a perfect fit. These holes should be 1/16" to 1/8" larger than the diameter of the all-thread to prevent thread damage and easy adjustment of the cross member. The length of the cross member should be sufficient to allow.
