2.5" Flat Slat Profile

This replacement component uses a nominal:

2.5" Flat Slat Profile

The formed slat interlocks with compatible adjacent curtain slats, allowing the rolling steel curtain to move vertically through the guides and coil around the barrel.

Because Cornell has produced multiple rolling-door curtain configurations, always compare the replacement profile with an undamaged existing slat before ordering.

End Lock Included

The current CDW configuration includes an end lock with the replacement slat.

Cornell uses end locks on rolling-door curtain slats to help:

• Maintain curtain alignment

• Control lateral slat movement

• Reduce wear

• Keep the curtain properly positioned within the guides

Cornell's current rolling-door literature confirms that end locks are attached to curtain slats to maintain alignment and help prevent wear during operation.

Commercial Rolling Door Construction

Cornell rolling service doors use interlocking roll-formed steel slats that form the flexible curtain assembly.

As the door opens, the curtain travels through the guides and coils around the counterbalance barrel. When closing, the slats uncoil and travel downward through the guides.

Properly matched slats and end locks are important for smooth curtain operation and alignment.

Replace individual slats when the curtain has:

• Impact damage

• Broken interlocks

• Excessive wear

• Missing end locks

• Damaged end locks

• Localized curtain damage

Replacing only the damaged curtain section can be a more economical repair than replacing the complete rolling-door curtain.

Curtain Inspection

When replacing damaged slats, also inspect:

• Adjacent slats

• End locks

• Vertical guides

• Guide bellmouths

• Bottom bar

• Astragal

• Barrel attachment

• Fasteners

Impact damage affecting one slat may also damage surrounding curtain components.

Important Compatibility Note

Cornell rolling steel doors have been manufactured with different:

• Slat profiles

• Slat sizes

• Gauges

• Curtain configurations

• End-lock styles

• Guide systems

• Door models

Before ordering, verify:

• 2.5" flat slat profile

• Existing slat shape

• Curtain width

• End-lock configuration

• Door model

• Required cut length

• Required color

Do not assume all Cornell rolling-door slats are interchangeable.

Measuring Replacement Slats

For replacement work, measure an undamaged existing slat from the same curtain whenever possible.

Do not rely solely on the nominal clear opening width because rolling-door slats extend into the guide assemblies.

Confirm the complete required cut length before ordering.
