This unique product from TURNSTILES.us is an excellent solution to your site security needs – with value-added engineering. Our buildings ship in pre-fabricated,  pre-drilled panels, saving on freight costs.  Enjoy all of the benefits that EntraBOX has to offer: save time and money and safeguard your site.

Specifications for Fiberglass Buildings


EntraBOX Equipment Options

EntraBOX Secure Modular Buildings are as versatile as you can imagine. Start with a body made of insulated Fiberglass Panels. Mix any color ink into the fiberglass during fabrication – your building can be the perfect color to match the surroundings or company color.  Flooring can be enhanced with nonslip surfaces. Add standard doors, roll-down doors, windows, entrance with turnstiles and access control, office, restroom, and more. Turnstiles, gates, and access control components make these excellent time and attendance buildings.

Our fiberglass buildings with turnstiles are permanent structures that stand on a flat foundation. See EntraBOX Portable Buildings for mobile buildings, and Portable Turnstiles for mobile equipment offerings.
