The Baby Pin Pro System: One Pin, Four Mounts

By Tomas HeinOctober 29, 2026

We all know the baby pin, so I won’t get into details. We’ve taken it and redesigned it with precision to fit all the standard uses, and much more.

The video shows the whole system, and the sections below follow it.

The Baby Pin Pro

The Baby Pin Pro is a precision-machined aluminium baby pin, 16 mm in diameter, with a hexagon collar on one end. Both ends are threaded 3/8"-16 UNC. It has a knurled grip section and is 4 inches (101.6 mm) long.

On a C-stand, a low boy or a knuckle it works exactly like a standard 5/8" baby pin. The difference is at the hex collar. It indexes precisely into the BLOQ and the HEX, and it locks into Super Clamps and grip heads the way a generic spigot never quite does.

On a tripod

In the video, the tripod’s baseplate has a 3/8"-16 thread, so the pin screws straight in. Tighten it by hand until it sits flat. The tripod now has a baby pin on top, ready for anything that takes one, including the Ellipse Base for the Lamina system.

On a cheese plate

A cheese plate has a threaded holes. A 3/8"-16 stud goes into the pin first, then into the back of the plate, as on the xLamina. From there the plate mounts on a C-stand knuckle.

BLOQ: the cart side mount

BLOQ mounts the Baby Pin Pro to the side of a production cart. A central hex socket takes the pin, and you lock it with a fixed stud and a hex key. There’s no protruding thumbscrew, so nothing catches, and it can stay on the cart when packed.

It fixes to the ends of Inovativ Voyager and Apollo carts with the included backing plate and 5/16"-18 screws. It also mounts on any cart with a standard 1/4"-20 grid using the included 1/4"-20 screws.

BLOQ also has 1/4"-20 and 3/8"-16 threaded holes with Arri and SmallRig locating pin holes. A magic arm or a monitor arm can go straight on the block without a pin.

CODO: the elbow

CODO is a pivot clamp that goes onto the pin and lets you angle whatever is on the other end. A friction washer gives continuous angle adjustment, and a lever locks the position by hand. It holds 5 kg at 90°.

The receivers are sized for the Baby Pin Pro and also fit standard 5/8" (15.88 mm) pins, so you can use it on a C-stand and then move it to a BLOQ on a cart.

HEX: the quick mount on the plate

HEX puts a baby pin interface on the back of the xLamina or any compatible cheese plate. It has two hexagonal parts. When they’re aligned, the pin slides in. Lock it, and the parts shift out of alignment and clamp the pin.

It’s 26 mm in diameter and 16 mm deep, so it sits flush against the plate. A single 3/8"-16 screw fixes it, and removable Arri-style M3 locating pins stop it rotating on plates with a matching thread grid. It’s made for the Baby Pin Pro only, and no other spigot fits.

Putting it together

The pin on the xLamina goes into the CODO, and the CODO sits on the pin in the BLOQ or a C-STAND. Set the angle you want and tighten. The plate is now on the side of the cart, angled where you need it.

To take it apart, release the CODO, then unlock the HEX, and the pin slides out. Both are released by hand. The BLOQ is tightened once with a hex key and then stays on the cart.
