CAST CONNEX® Diablo™ Bolted Splices are cast steel fittings that enable unobtrusive field bolted splices in circular hollow structural section (HSS) members. The fittings are designed such that the bolted connection is inboard of the outer diameter of the HSS. Splices made with Diablo Bolted Splices can be sheathed in thin-gauge plate to completely conceal the splice or can be left uncovered for a sleek, technical connection aesthetic.
Diablo Bolted Splices are supplied including drilled bolt holes. All of the fittings can accommodate four fasteners, though our fittings for 12.75-inch (324 mm) outer diameter HSS can also be supplied to accommodate 8 fasteners. Hand wrenches must be used for bolt tensioning in the field. Fasteners are not included and cover plates (if required) are sold separately.
