The new P&C Swiss Rod adds simple mounting solutions for DSLR accessories onto your standard 15mm DSLR Video rigs. It is not designed to replace all of your 15mm rails, but with just one Swiss Rod clamped to your rig, you have 20 different mounting options to choose from. You can attach an accessory directly or for more flexibiltiy add a friction arm, quick release, or cold shoe adapter to the Swiss Rod. The Swiss Rods have both male and female threaded ends so they can be extended. Threads are standard and I have attached them directly to Gini rails and even the Letus DSLR cage.
[Update] Sorry International Buyers. Shipping + Tracking information is pretty expensive. In order to make it worth the shipping fee, a minimum of 4 pcs need to be ordered.
