Buying Guide: Key Purchase Considerations
What type of ceiling do you have? For flat ceilings, a trim collar with a seamless finish is ideal. For angled ceilings, a sloped ceiling plate offers adjustable fit. If you need wall-mounted support, choose a stainless steel bracket sized to your pipe diameter. Always confirm pipe size, ceiling material, and heat exposure to ensure compatibility with the collar or bracket you choose.
