Our take on the SmallRig 15mm Railblock
The SmallRig 15mm Railblock is a rod clamp with two 15mm rod holes and standard quarter inch threads, for streamers building a camera rig. At a tracked $14.99 it was flat across three points from August 25 to October 1, 2026.
In a rig, it joins two 15mm rods, which lets you add a monitor, light or mic arm to a camera cage. The pack has two clamps, four short and four long screws, and a hex key. It is made from aluminum alloy and weighs 90 grams. It has 4.8 across 1,475 retailer ratings, a very strong score at this price. It only helps if you already use 15mm rods.
