This is a perfect back plate for a 1.5 inch TC element enclosure. It has a 1 inch hole for a strain relieve and a threaded screw hole for grounding. A little slot acts as a safety drain port in the event you have a leak
Please note: Canada Post is now on strike so I will be shipping your package via alternative carriers such as UPS, Canpar or FedEx. The rates are similar enough that you can checkout with Canada Post as the shipping option. If there are any major discrepancies, I'll reach out to let you know prior to shipping. Hopefully this will be resolved quickly. Feel free to reach out with any questions or if you want a shipping quote before placing your order.
