This is a replacement part for the blocks that go under the seats (cushions) in many consumer-level boats, to keep the seats lined up and in-place.

The original block measures 100mm x 19mm * 25mm, with screws spaced 53mm. This part duplicates those dimensions.

Buying the real part is very cheap, but if it's not available locally, the shipping tends to be very expensive.

You may choose lower in-fill and more shells, as this part does not need to be strong, and was designed solid rather than hollow like the original.
