Heavy-duty storeroom knobset

The Yale 780H-605 is a Grade 3 certified knobset built for commercial storeroom use. Its fixed outside knob requires a key for every entry while the inside knob remains free for exit. A solid brass 5-pin cylinder with Kwikset KW1 keyway operates the guarded latchbolt. Concealed holding screws give a clean finish on standard doors.

Best for controlled-access rooms

This lock suits storage areas, utility closets and back offices where the outside must stay locked at all times. It is not for passage doors that need unlocked entry from either side, nor for privacy functions that lock from the inside only. Builders needing a deadbolt or an entrance function should select a different product.

2-3/8 inch backset decides fit

The latch is factory set for a 2-3/8 inch backset, the most common residential and light-commercial dimension. Verify the existing door preparation matches this measurement before ordering. A 2-3/4 inch backset door will not align without re-boring.

Questions about this item

How often will the 5 pin brass cylinder with Kwikset KW1 keyway need lubrication or replacement?

The solid brass 5 pin cylinder with Kwikset KW1 keyway is built for heavy duty storeroom use; periodic graphite lubrication once a year keeps it operating smoothly and replacement is rarely needed under normal traffic.

What limits continuous operation on a high traffic door?

The A156.2 ANSI/BHMA Grade 3 certification and 90 minute UL rating define the endurance ceiling; beyond very high cycle counts the latch mechanism will show wear before the finish or cylinder.

Does the polished brass US3 finish or knobset generate noticeable heat or noise after all day use?

The mechanical knob and latch produce only a light click on each operation with no heat buildup; the polished brass US3 finish stays cool to the touch even during constant daily traffic.
