32" x 72" BA-CORHSR Compression Roof Hatch Safety Railing

The 32" x 72" BA-CORHSR Compression Roof Hatch Safety Railing is an OSHA-compliant, patented guardrail system engineered to provide fall protection around existing roof hatch openings.

Designed with adjustable width and length, it clamps directly onto curb counterflashing or can be mounted underneath, without penetrating or drilling into the roofing membrane.

Accommodating hatches from 24" x 24" up to 48" x 96", this field-adjustable system includes a standard self-closing, self-latching gate. The system is designed to meet OSHA fall-protection requirements and is tested for the loads referenced in OSHA 1910.29, ANSI A1264.4, and 2024 IBC 1607.9 (ASCE 7).

Why Choose 32" x 72" BA-CORHSR Compression Roof Hatch Safety Railing?

• Precision Code-Compliant Height Adjustment: Three vertical mounting positions allow the corner posts to be adjusted, so the top rail sits 42 inches above the walking surface, as required by OSHA standards.
• No-Drill Counterflashing Compression Mount: Patented compression design mounts directly to the curb counterflashing (or underneath), eliminating roof membrane penetrations.
• Field-Adjustable Fit: Adjustable width and length let the railing fit many manufacturers' hatch designs and sizes.
• Durable Galvanized Steel: The guardrail uses 16-gauge galvanized steel tubing which stands up to rooftop weather and repeated use.
• High-Visibility Finish: A safety yellow powder coat keeps the railing clearly visible on the roof.
• Included Self-Closing, Self-Latching Gate: Ships complete with a telescoping self-closing gate featuring adjustable steel spring hinges and a black powder-coated pin lock.

What to Know About Installation Requirements?

Fitting the Railing

The BA-CORHSR clamps around the roof hatch curb using its compression-mount system, then the fittings are tightened to hold it in place. Confirm the railing size against your hatch opening before installation.

Installation Notes

• Mounting Position: Align compression brackets around the hatch curb counterflashing (or position underneath the counterflashing).
• Compression Attachment: Tighten zinc-plated compression hardware securely around counterflashing.
• OSHA Height Calibration: Secure corner posts into one of the three vertical bolt hole settings on the brackets. Verify that the top rail measures 42" above the walking surface per OSHA 1910.29(b)(1) and 2024 IBC 1015.3.
• Gate Setup: Adjust the telescoping gate width to match the opening, ensuring the spring hinges hold the gate closed, and the black pin hooks cleanly into the gravity latch catch.

For fall-protection and rooftop-access requirements, review the OSHA walking-working surfaces standard and confirm details with your design team.

Frequently Asked Questions About Compression Roof Hatch Safety Railings

How does the compression mount work?

The railing clamps onto the roof hatch curb counterflashing with compression fittings, so it holds securely without drilling into the roof or curb.

Can it be mounted below the counterflashing?

Yes. While designed primarily to mount on curb counterflashing, the submittal notes it can also be mounted underneath.

How do I ensure compliance with OSHA rail height regulations?

Install corner posts using one of the three pre-drilled vertical bolt holes to ensure the top rail sits at 42" above the walking surface per OSHA 1910.29(b)(1).

Will it fit an oversized hatch?

Custom sizing is available for non-standard or oversized hatches and roof openings.

Why buy roof safety products from Best Access Doors instead of a general marketplace?
