I just received my very well made and solid pellet trap from Archer Airguns.
The opening can accomodate a 5.5"x 8.5" target which is supported by the supplied cardboard cut out. A nice feature eliminating the need for clips, staples etc. The target and cardboard slide very smoothly in the trap grooves. Pic below
In the picture below you can see how perfectly a standard "duct seal" bar from Home Depot fits. (or purchased at Archer's). The trap is deep enough for multilpe layers.
The feature I like most is its deep lip in front bottom (see pic below). It would prevent any putty chips or any lead debris from falling out and possibly trashing your room.
This is a quality trap that should last for years when properly used and when not in use it could blend nicely with your furniture. 
It should make the winter or indoor shooting sessions a lot tidier and much more pleasant with its quiet feature.
