The Botanicare® TriLock™ Trellising Support is an optional upgrade for Botanicare® Slide Bench systems. We understand that your grow is unique. That’s why we’ve developed options to improve your experience with a more robust trellising support designed to enhance the rigid connection to the bench. The TriLock™ Trellising Support is three times stronger than the standard support and accepts three different trellising types - ¾” EMT, ¾” PVC & 1” EMT.
