Matthews has announced its latest grip solution, the 5/8″ Grip Rail -Telescoping Baby Rail. This is a fully adjustable 5/8″ rail featuring a telescoping 5/8″ baby pin that closes to 24-in / 62 cm and extends to 42.5-in / 108 cm.
The telescoping baby rail is ideal for working in confined spaces. Instead of dealing with a standard grip arm’s full length, the Telescoping Baby Pin adjustable rail extends only as far as the job requires. There is no fitting, transporting, or storing of individual extenders.
Matthews’ solid stainless steel inner rod keeps everything rock solid under load, and it is claimed to have no flex, no sag, and no bow. Alternating two-inch hash marks and flat spots facilitate dial-in, repeatable positioning, and lock-down to prevent roll.
The system features an internal stop to guard against section separation. Additional precautions include: a knurled undercut on the rugged steel baby pin to keep fixtures from slipping if loose, and a safety hole for a cotter or lynch pin with a tapped female 1/4″–20 thread that converts to male 1/4″–20. It all locks down with a Matthews T-handle or a field swappable grub set screw.

The Telescoping Baby Rail weighs just 2 lbs / 0.91 kg, and it supports 10 lbs / 4.5 kg horizontally and 20 lbs / 10 kg vertically.
