This solved my lighting problem and when I contacted the shop owner, they were very quick to respond and really helpful. I highly recommend this product to anyone who needs an adapter fix for a light. I got a size slightly too short but it is still holding my light and itÕs sturdy.
Very good seller, shipped very fast and worked out perfectly!!
I needed to mount a WeekAqua light on a rimmed aquarium and these lights are heavy. I tried 2 different 3D printed brackets and both snapped from the weight of the light. I had over looked this option because I wasn't sure how this mount would hold up. The build quality and the ability to have screws in the front and back, really holds this bracket securely on the aquarium. If you need to mount a rimless light mount on a rimmed aquarium. Look no further.
Good communication. Custom order was what I needed.
Very useful adaptor to attach lights to prefabricated aquarium tanks with plastic rims.
