High Clearance Arch Series
High Clearance Arch
Our High Clearance Arch System is designed for use with boring pits, large diameter pipe installation and any other application where a vertical clearance of 10′ is needed.
- Full range of bolt-on extensions to allow up to 22′ inside width.
- Allows 8′ of vertical clearance when used with 8′ high shields.
- Professional Engineer depth certification.
- Custom designs and sizes are available to meet any job requirements.

Stone Boxes
SB Models are designed to be used with lighter machinery. They are constructed of 1/4″ thick side plate with 1/2″ bottoms.
S B H Models are intended for use with heavier equipment. They are constructed of 3/8″ thick side plate with 1/2″ bottoms.
S B W Models are designed for larger buckets. These Stone Boxes are wider for that reason. They are constructed of 3/8″ side plates and 1/2″ bottoms.
