24-1/4'' Replacement Lens / Cover / Diffuser for Low Profile T5 Series Under Cabinet Fluorescent Fixture. Size: Depth - 2-3/4'' x Height - 1'' x Length - 24-1/4'' RCAL24.25, Translucent White

I bought this to replace builder installed diffuser that cracked. The size and price were right, so I ordered it. It arrived a few days later than expected for reasons unknown, but at least I got a notice from UPS so I knew when it would actually arrive.The product is well made; the only issue is that it is thicker than the original piece and much more rigid, which made it quite difficult to install on an under-counter light; it must be bent slightly to get it into the slots on the fixture and due to the rigidity and limited room under the counter, it was a challenge to get it on. It will be the same challenge if a bulb goes out and the diffuser has to be removed to change the bulb. However, the extra thickness and rigidity should make this more durable than the original that came with the fixture.This product also seems to allow the light to be a bit brighter than the others -not enough to be annoying, but just something I noticed.Other than its thickness and rigidity, which in one way could be considered a plus (except when installing it) this is a good one of its type, so four stars out of five
