It is designed to provide reliable floor access while maintaining a neat interior finish, making it well suited to residential, commercial, and service spaces where appearance and functionality both matter.

Can the internal access hatch be installed in an existing floor?

Yes. The hatch can be incorporated into retrofit projects as well as new construction, subject to site conditions and structural requirements.

How customizable is the hatch?

Surespan offers a wide range of custom sizes, finishes, and operating options so the hatch can be matched to the surrounding interior design and access requirement.

Enhanced Safety Options

Safety Products

Additional safety options for internal floor hatches include a pressure-sensitive edge for electrically operated units, a retractable handhold for assisted entry and exit, a Ladder Up Post for vertical access, and a safety grid for fall protection when the hatch is open.

Enhanced Access Options

Ladder Access

Internal access hatches can be paired with ladder types selected to suit the room layout and available floor area. Standard straight ladders provide direct access, while spiral or compact ladders help in tighter footprints. Folding ladders are also available where the access route needs to remain unobtrusive when closed.
