Schlage AL40S SAT - Standard Duty Privacy Lever Set - Saturn Style

The Schlage AL40S SAT is a Grade 2 standard-duty privacy lever set in the Saturn lever style, conforming to ANSI function F76. The inside push button locks the outside lever. The inside lever is always free for immediate egress. Closing the door automatically resets the push button, so the outside lever returns to its operable state when the door shuts. From outside, a small screwdriver inserted into the hole in the outside rose retracts the button for emergency access without a key. Certified to ANSI A156.2, 1996, Series 4000 Grade 2. UL listed for 3-hour fire door assemblies. ADA compliant per ANSI A117.1. Three-year limited warranty.

How the screwdriver emergency override works on the AL40S

The emergency outside access mechanism on the AL40S SAT is one of the most important operational details for facilities that specify privacy function on patient rooms, hotel guestrooms, or single-occupancy restrooms. When someone on the outside needs to open the door and the inside push button is engaged, inserting a standard small screwdriver blade into the slot on the outside rose retracts the button without a key, without a special tool, and without damaging the hardware. The lock resets normally after entry.

This is the mechanism that gives privacy function its place in commercial and institutional applications over other lockout configurations. It allows immediate staff access in medical emergencies, wellness checks in hospitality, and building management entry in multi-family buildings, all without a key management overhead. No master key is needed, no call to building services for a key, just a tool any staff member can carry. This behavior is exactly what ANSI F76 specifies as the outside override method for privacy function, and it's why the AL40S is specified across hotel guestrooms, medical exam room restrooms, office suite bathrooms, religious facility restrooms, and government building restrooms where key management for individual doors would be impractical.

Saturn lever style, ADA compliance, and construction details

The Saturn (SAT) lever is a rounded, smooth contemporary profile suited for commercial design environments that call for a clean, uncluttered lever shape. The lever returns to within 1/2" of the door face, which satisfies ADA requirements under ANSI A117.1 for accessible door hardware. It operates without tight grasping or twisting and requires no more than 5 pounds of force, meeting the operational force limit for accessible hardware on any commercial door subject to ADA review.

The chassis is steel, zinc dichromated for corrosion resistance. True through-bolting of the door body prevents the chassis from rotating or disengaging from the latch under lateral stress. Cold-rolled steel threaded hubs with locking nuts keep the trim assembly from loosening under the repeated push and pull traffic that high-use restroom doors experience. Heavy-duty compression springs maintain lever return speed and crispness and extend spring cage life compared to standard torsion spring designs. A patented door range adjuster handles door thickness from 1-3/8" to 1-7/8" without additional hardware, which simplifies installation on mixed door schedules.

Finishes, backset options, and ordering specifications

Three finishes are available: 626 satin chrome (standard), 619 satin nickel, and 606 satin brass. Backset is 2-3/4" standard with a 2-3/8" option. The standard strike is an ANSI curved lip 4-7/8" x 1-1/4"; a T-strike 2-3/4" with dust box is also available. The latch bolt is brass with a 1/2" throw. Exposed trim is wrought brass or bronze; levers are pressure-cast zinc plated to match the trim finish. The lock face carries both the letter F and the UL symbol, confirming fire-rated listing at point of inspection without having to look up the listing separately.

Select your finish, backset, and strike type when ordering. Confirm door thickness falls within the 1-3/8" to 1-7/8" standard range before specifying the AL40S SAT.
