I have a couple of these displays (one smaller one and one larger one) for multiple cards.
Since PSA slabs have no stated UV protection (and my research indicates there is none), I looked into various options for displaying my graded cards (mix of PSA, BVG, BGS, and SGC, plus some one-touches). I'm happy with these with respect to UV protection (they sent me the data sheet for the UV acrylic they use) and the frames themselves are well built and not too costly for what you're getting.
There are a non-trivial amount of Chinese knock-offs on eBay and elsewhere, so be sure you're getting from their eBay store or direct from their website (mainly to ensure getting the UV protection). They also stand by their products and were super responsive in solving a minor finish/damage issue.
They have a number of configurations (and were helpful in pointing me to the right one) in their online chat.

I have no affiliation but was very happy with the product and their customer service. Not cheap, but fairly cost effective (and my wife approved of the decor).
EDIT: I did replace the inexpensive snap closure they used with some magnetic latches. PM me if want specifics, was a quick fix.
