AI HMS Rail 36"

The AI HMS Rail 36" is sized for aquariums from 25 to 36 inches long, giving you a rail to mount multiple Hydra LED lights in a row for even coverage across the tank. The rail itself measures 37.5in — sized 1.5in longer than its rated tank length for proper end clearance. Fits aquariums: 25in to 36in long Actual rail length: 37.5in Compatible with: all Hydra LED light models and versions Requires: HMS 2-ARM kit or HMS Hanging Kit (sold separately) to mount the rail itself Sizing rule of thumb: add 1.5in to your tank's total length and choose the closest HMS rail size that's longer than that number. Compatible replacement parts: HMS brackets and arm/hanging kits for the 36in rail.
