Not sure which cover you have?
Most fit problems come from one measurement. We’ll help you get it right before you order.
1. Measure your cover
Step-by-step guide: length, width, depth and width between the hooks.
2. Use our Trace & Send form
Trace the end profile of your cover and send it to us. We match it to our molds.
3. Text us a photo
Send a picture of the cover and fixture label to 617-867-5078. We'll reply with a match or a quote.

Can't find your cover online?
Not every style we make is listed here. Send us the measurements, a photo, or the broken cover itself, and we’ll quote a custom-molded replacement at no cost.
Ordering & shipping
Covers listed in the shop are stocked and usually ship within 5–7 business days. Inventory moves throughout the day, so if an item sells out we’ll contact you before shipping. See our shipping info and return policy.
Buying for a building or contractor?
Replacing covers is usually far cheaper than replacing fixtures. For schools, offices, hospitals and property managers we offer bulk and wholesale pricing.
