Description of BUD Industries HH 3550 Plastic Grabber
Uniquely shaped enclosure is more ergonomically designed than most other enclosures. Durable self-extinguishing ABS plastic material with UL94-5VA flammability rating. Mar resistant textured surface with internal PCB mounting bosses. Base is securely attached to cover. External measures 4-1/2" length by 4-1/2" width by 1-1/2" height; internal measures 4-17/64" length by 4-17/64" width by 1-1/4" height.
This is a surprisingly strong and beautifully spacious design, even for multiple boards or complex prototypes. It's a bit odd in shape, making it both interesting for end users and annoying for mass production, but overall it's worth a look.
