An important feature to remember with Splice Bolts is that they are manufactured with a smooth head, so that when you use them to install a splice or other accessory into a tray or ladder there is no risk of sheathing your cables. The bolts used on tray systems are generally hot dip galvanised, while on ladders you can choose between hot dip galvanised or stainless steel versions, depending on your corrosion protection needs.
