Sonic Foam System - Wrench Set - 30 Pieces - 1/3 (Small) Subtype - Water Filtration Back hole is 2 3/8"

Back hole is 2 3/8" and the front hole is 6 1/8" off the back wall

Sonic Foam System - Wrench Set - 30 Pieces - 1/3 (Small) Subtype - Water Filtration Back hole is 2 3/8"These are the tools I've decided to use at OGHQ, they have a nice quality to them with good ergonomics. They aren't intended to replace everything but there is a great variety of tools offered here. For the price, you cannot beat them vs something that's 2x or 3x the cost like Snap On.
