This is the V-Slot Universal Plate. It can be used on all sizes of V-Slot. 20 x 20mm 20 x 40mm 20 x 60mm 20 x 80mm The idea behind this plate is to simplify construction. We wanted to ensure that we simplify belt clamping so we have incorporated ‘Fold-Through’ Slots to allow you to easily fold the timing belt teeth back onto themselves and zip tie or clamp them in place. We have also added two 5mm slots that allow you to attach spacers for 90 degree belt mounts under or on top of the plate as well. This simplifies the overall building process and allows for quick assembly times of motion systems. There are a lot of possible mounting configurations for this plate. 6063-T6 Aluminum Black Anodized Finish 3mm~ (1/8″) Thick
