Frequently Asked Questions
Will this block fit 19mm studio rods?
No. The Rod Bloc is specified for 15mm LWS rods only. A 19mm studio rod system needs a different block or a 19mm-to-15mm rod adapter for compatibility.
Can I mount both a 1/4-20 and a 3/8-16 accessory at the same time?
Yes. The block has one 1/4-20 and one 3/8-16 threaded hole, so two accessories with different thread standards can be mounted to the same block simultaneously.
Is the aluminum construction strong enough for monitor arms or EVFs?
The block is CNC-machined from aircraft-grade aluminum, which is the standard material for this class of rig accessory. For very heavy loads, supporting the accessory with a second mounting point is best practice.
Does it include anti-rotation pins for locking accessories in place?
The product description lists only the threaded holes — no integrated locating pins are specified. Accessories that need anti-rotation will rely on friction from the threaded fastener and mating surface.
Is this block suitable for gimbal builds where weight matters?
Yes. Aluminum construction keeps the block lightweight, which matters on gimbal and handheld rigs where every gram affects balance and battery life.
