About this item
The Imperial-USA DL-LSV60-US26D is a standard duty Grade 2 cylindrical double cylinder lever set in satin chrome (US26D) for light commercial and residential applications where both sides of the door require key control. The key in the outside lever locks or unlocks the latch from outside; the key in the inside lever does the same from inside. Each side operates independently. ADA compliant lever, non-handed and reversible body, solid zinc diecast construction. Schlage "C" keyway with six-pin keying integrates with existing Schlage-keyed buildings. SKU DL-LSV60-US26D. In stock. Configurable for Standard, Keyed Alike (KA), or Master Keyed (MK) keying.
About the Double Cylinder Function
A double cylinder lever set is a specific function code, not a general lock category. Both the outside and inside levers require a key to operate the latch, so neither side can be unlocked from inside without the key. Most common applications are light commercial back-of-house doors with adjacent glass that would otherwise allow a reach-through to a thumbturn, secondary security entries, vault and equipment rooms, and back doors on retail or service spaces where the inside-key requirement is acceptable to the building code that applies. Verify the local egress code before specifying this function on any door used as a primary entry or required exit. Many jurisdictions restrict double cylinder hardware on egress doors because the inside-key requirement conflicts with free-egress requirements.

When to Specify the DL-LSV60-US26D
Three patterns drive most orders for this SKU. First, light commercial doors with glass panels or sidelights where a single cylinder lever with a thumbturn would create a reach-through vulnerability. Second, retail or office back-of-house entries where both sides require key access to control after-hours staff and vendor access. Third, residential applications on secondary doors (basement, garage entry, secured storage) where both-side keying is preferred for security and the door is not a primary egress route under the local residential code. The Grade 2 ANSI/BHMA certification puts the DL-LSV60 in the light commercial and residential bucket; it is not intended for institutional Grade 1 applications such as schools, hospitals, or government buildings.
Compatibility and Retrofit Notes
The 2 1/8" bore preparation matches the standard cylindrical lockset cutout used by virtually every residential and light commercial door in the United States. The 2 3/4" backset matches the standard residential and commercial spec. The Schlage "C" keyway is the most common keyway in North American residential and light commercial buildings, so this SKU integrates into existing Schlage-keyed master systems without rekeying the rest of the property. Door thickness range 1 3/4" to 2" covers virtually all standard interior and exterior commercial doors.
