Overview: What Is the Yale 8835FL?

The Yale 8835FL is a heavy-duty exit mortise lever lock designed for commercial door applications requiring both panic egress and mortise lock security. It combines a mortise lock body with a lever trim on both sides, making it one of the most versatile and widely specified exit mortise devices in the commercial hardware market.

The "FL" designation refers to the lever trim configuration — lever both sides — distinguishing it from other Yale 8800 Series configurations that use different trim combinations. The 8835FL is part of Yale's 8800 Series, which is engineered for high-traffic institutional, commercial, and educational applications.

Fire Rating and Code Compliance

The Yale 8835FL is UL-listed for use on fire-rated door assemblies up to 3 hours (UL 10C positive pressure). This makes it suitable for the most demanding fire-rated openings in commercial construction, including stairwell doors, corridor doors, and other fire-barrier openings.

The device also meets:

• ANSI/BHMA A156.3 Grade 1 — the highest grade for exit devices
• ADA Standards for Accessible Design — all standard lever trims comply
• NFPA 101 Life Safety Code requirements for panic egress
• IBC (International Building Code) requirements for exit hardware

How to Order the Yale 8835FL

Yale exit mortise locks are ordered using a structured product code. A typical 8835FL order string looks like this:

Example: Yale 8835FL x F05 x 10 x 626 x RHR

• 8835FL — Base model (exit mortise, lever both sides)
• F05 — Function (Office)
• 10 — Lever style
• 626 — Finish (Satin Chrome)
• RHR — Handing (Right Hand Reverse)

Handing is determined by standing on the outside (key side) of the door and observing which side the hinges are on. Right Hand (RH) = hinges on right. Left Hand (LH) = hinges on left. Reverse handing applies when the door swings toward you.

Installation Notes

• The 8835FL requires a standard ANSI mortise prep (ANSI A115.1) in the door edge.
• Verify the door thickness before ordering — standard is 1-3/4". Spacer kits are available for non-standard thicknesses.
• The device is field-reversible for handing, but it is best practice to order the correct hand to avoid field modification.
• Cylinder is not included — order separately. The 8835FL accepts standard Yale or SFIC (Small Format Interchangeable Core) cylinders.
• Strike plate must be ordered separately and matched to the door frame material and profile.

Cylinder Options

The Yale 8835FL accepts the following cylinder formats:

• Yale Standard Cylinder — 6-pin, keyway options available
• SFIC (Small Format Interchangeable Core) — compatible with Best, Arrow, and other SFIC systems for master key flexibility
• Schlage C Keyway — available for projects on Schlage master key systems

Frequently Asked Questions

Is the Yale 8835FL the same as the 8800FL?

No. The 8800 Series is the product family. The 8835FL is a specific model within that family. Other models in the series include the 8827FL (exit mortise with thumbturn inside) and the 8847FL (exit mortise with deadbolt). Always specify the exact model number.

Can the 8835FL be used on a fire-rated door?

Yes. The 8835FL is UL-listed as fire exit hardware for assemblies up to 3 hours. It is one of the few exit mortise devices rated for 3-hour assemblies.

Does the 8835FL include a cylinder?

No. The cylinder must be ordered separately. Specify the keyway and cylinder format when ordering.

What is the warranty on the Yale 8835FL?

Yale provides a limited lifetime mechanical warranty on the 8835FL for commercial applications.
