This 4-Sided Top Shelf for Voyager 36 with Threaded Rail Plates from Inovativ is a replacement top shelf for the Voyager 36 NXT or EVO cart system and can be used with either the NXT or EVO cart. Featuring a lightweight yet strong 5052 aluminum construction with a custom outdoor carpet, the cart top is ready to serve through all manner of weather. The carpet protects your gear from metal-to-metal contact and helps hold small components so they don't roll around, while the raised sides help prevent smaller items from rolling off the shelf, even when the cart is rolling.
