Penetrations & AccommodationsDesigning for New and Existing Field Equipment
Are custom holes and cutouts available for wiring and instrumentation?
Yes. Shelter Works provides custom-engineered access and penetrations for wiring, conduit, pipe, instrumentation, and more. These factory-installed modifications are determined during the submittals process to ensure proper placement and fit. Whether you need a simple pass-through for new equipment or a way to accommodate existing equipment, we work with your layout to place openings exactly where they are needed. This reduces on-site modifications, preserves the integrity of the enclosure, supports faster installation, and maintains the shelter’s 25 year warranty.


Wall Penetration Options

What are Bulkheads?
A fiberglass area of wall that allows you to cut through the fiberglass without exposing the core materials. This preserves the shelter's structural integrity when field penetrations are required.

What are Formed Openings?
Reinforced fiberglass encapsulated openings for vents, roof hatches, HVAC, and more. Typically used for factory-installed equipment, they are also used for field-installed equipment that runs through a wall.

What are Knock-out Panels?
Removable portions of a wall, held in place by an aluminum trim kit, that are useful for installing enclosures over existing pipes. They allow for 360° access to equipment, enabling you to make field cuts to accommodate established stations.
