One Tool, Infinite Reach: Matthews Solves the Confined-Space Rigging Problem
![]() |
|
Matthews Studio Equipment introduces the 5/8" Grip Rail - Telescoping Baby Rail, a fully adjustable grip solution built to replace a whole quiver of fixed-length 5/8" rods with a single tool. The telescoping baby pin closes to 24" (61cm) and extends to 42.5" (108cm), so it extends only as far as the job requires -- no fitting, transporting, or storing individual extenders.

Key Features
-
Telescoping Design: Adjustable 5/8" rail closes to 24" (61cm) and extends to 42.5" (108cm), eliminating the need for multiple fixed-length rods
Solid Stainless-Steel Inner Rod: Keeps everything rock-solid under load, with no flex, sag, or bow - Dial-In Positioning: Alternating 2" hash marks and flat spots enable repeatable positioning and lock-down to prevent roll
- Built-In Safety Stops: Internal stop guards against section separation
- Secure Baby Pin: Knurled undercut keeps fixtures from slipping if loose, with a safety hole for a cotter or lynch pin
- Versatile Mounting: Tapped female 1/4"-20 thread converts to male 1/4"-20 for camera and accessory mounting
- Flexible Locking: Locks down with a Matthews T-handle or a field-swappable grub set screw
Ideal for Confined Spaces
The Telescoping Baby Rail is built for the tight quarters where a standard grip arm's full length becomes a liability -- car interiors, small bathrooms, and other cramped set environments. Instead of carrying a bag of fixed-length rods to cover every possible distance, grips and cinematographers can carry one tool that adapts to the space instead of forcing the space to adapt to it.
Despite weighing just 2 lbs (0.91kg), the Grip Rail is rated to support up to 10 lbs (4.5kg) horizontally and 20 lbs (10kg) vertically, making it equally suited to a lightweight monitor or a professional lighting fixture.

Built for the Rigors of the Set
True to Matthews' reputation for durable grip gear, the Telescoping Baby Rail's solid stainless-steel inner rod resists bowing or bending under load. The alternating 2" hash marks and flat spots make dial-in, repeatable positioning simple, while the internal stop prevents the sections from separating mid-shot.
Safety details are built into the hardware: a knurled undercut on the rugged steel baby pin keeps fixtures from slipping if they loosen, and a dedicated safety hole accepts a cotter or lynch pin for extra insurance. A tapped female 1/4"-20 thread converts to male 1/4"-20 with the included set screw, giving it a seamless interface for cameras and smaller accessories. It all locks down with a Matthews T-handle or a field-swappable grub set screw.
A Modular Ecosystem
The 5/8" Grip Rail is designed to integrate with existing production gear. It can be secured in a Matthews BabySitt'r for low-profile floor mounting or paired with a standard 2.5" Hollywood Grip Head. For mobile creators, it also works alongside tools like the White Dinkum FlexiMount, becoming a foundational element for overhead shots, recipe videos, and behind-the-scenes documentation.
