This is the 5-pack of 3’3” (1 meter) Extender Rails. Each are pinned and allow travel across the seam.
The one meter Extender Rails have a variety of uses. When added to the standard 2-meter Rail, they can be used with the Auxiliary Trolley to aid in the festooning of vent tubing, or with the Add-A-Lamp components, they can enable two grow lights to run in a 9 foot (3 meter) configuration instead of a 12 foot (4 meters) configuration. Another use might be to run indoor garden lights over a 9 foot (3 meters) area instead of a 6 foot (2 meters) area during situations when less light is needed such as early growth/seedlings or with low light plants. The Extender Rail is compatible with LightRail 3.0, 3.5, 4.0 and 4.20 and comes with pins, allowing a Motor to cross the seam of the Rail.
Suspended Rail Note: It is important to properly support a suspended Rail in a greenhouse setting. In addition, it is recommended to make a “splint” by drilling the combined Rail seams onto a small piece of wood, providing extra strength needed at the Rail seam.
