The Screwless Surface Mount Frame is designed to solve the hard to be assembled problem that the old type surface mount frames have. It is very easy to install, save 80% labour cost.

Of course you still need the screws to fix the frame to the ceiling.  Then it is almost done:
First pull the side which is with two springs on, then slide the LED panel into the frame .  At last, leave your hand, it is finished.

The surface mount frame has enough depth to accommodate the LED driver.
