HO OO Adjustable Track Spacing Tool 2 Pack, Model Railroad Parallel Rail Alignment Gauge with M3 Thumb Clamp, Metric or Inch Scale, Track Laying Aid for 16.5 mm Gauge Layouts (Inches)

Set consistent parallel track spacing while building or adjusting your HO/OO model railroad layout. This 2-pack of adjustable track spacing tools helps you position flex track, sidings, yard tracks, display tracks, and parallel runs without measuring the same distance over and over. Each tool sits over HO/OO 16.5 mm gauge rails using a fixed rail saddle and a sliding rail saddle. Move the sliding saddle along the marked measuring bar, then tighten the M3 thumb clamp to hold your chosen spacing. Choose either the metric version or inch version when ordering.

• DESIGNED FOR HO/OO 16.5 MM TRACK: Built for HO/OO gauge model railroad track with saddles that sit over the rails to help position consistent spacing between parallel tracks.
• ADJUSTABLE WITH THUMB CLAMP: Sliding saddle moves along the measuring bar and locks in place with an installed M3 thumb screw clamp, making it easy to return to the same spacing.
