How to cover a cable tray with a right-angled cable tray
The TX bracket allows you to fabricate tee or cross combinations in the ET/ET3/ET5 tray. Simply make the appropriate cuts in the side wall of the tray you are joining a length to, bend down the side wall, and attach a TX bracket either side.Always use 2 splice plates per length of tray and SBH and CNH splice nuts and bolts to fasten them in place. EzyStrut splice bolts have a smooth head which should be installed on the inside of the tray's side wall. The SBH's smooth head is specially designed so it cannot damage any cables.The radius plate comes in a standard 2m length, and the amount of fasteners you will need to install will vary depending on the angle and size of the desired bend and tray that you are using.The ET range of trays are generally secured onto strut with hold down units. Always install them in pairs, and always secure a tray at least twice along its length.Riser links must always be installed in pairs, one on each side of the tray. The quantities that you will need to use will vary depending on the size of the riser (internal or external) that you are fabricating. If ever you need any help, EzyStrut staff know our products, and can demonstrate them.
