The 125B enclosure: It's die-cast aluminum. It's shrink-wrapped. It comes with four screws.
And, in my opinion, the aluminum machining looks way nicer and more finished than what I used to get from the big suppliers (before I started sourcing my own).
There are LOTS of different pedal enclosures called the 125B on the Internet, all based on the 125B Hammond enclosure. Please check my measurements to make sure you order the enclosure that matches your required specs.
The 125B enclosure measures 121 x 66 x 39mm (4.7 x 2.6 x 1.5") and fastens with four screws
