Hollaender is the originator of the Speedrail fitting and Speedrail itself so it's pretty easy to understand why they are the best. Without getting into a ton of technical information which lets be honest, it all sounds greek anyway, these Speedrail Fittings rock! Each with two set screws to keep them tight, and no you don't have to go crazy tightening set screws, they grab the pipe very easily. The Speedrail Short Barrel Cross or SBC is a variation of the Cross. It is just as strong, but takes up less real estate on the rails or in your cart. Short Barrel Crosses are probably one of the most widely used Speedrail Fittings. Used for a multitude of car rigging applications as well as most any rigging, the Speedrail Cross is in the mix no matter what kind of rig you are building. Buy them in the dozens, you will use every one.
