Absolutely ideal for using as a ramp extender so that wheeled flightcases can be pushed into a trailer much more easily. Perfect size, lightweight but more than solid enough for very heavy wheeled flightcases. Buying a second one to bridge a gap at the top of a trailer ramp. Arrived on time. Very happy!
Sturdy, Good Value.
Front flap has about 1/4 inch play to adjust to the height of the floor.
If the flap doesn't slide into the ramp... mine had burs behind the two threaded holes.
Took a rotary tool with a small bit (or use a small round file) and knock them off - parts slid together fine.
