The DELTANA SDL980U3-UNL is a round tubular storm door latch finished in unlacquered bright brass. It is designed for residential and light commercial storm door applications where a durable, corrosion-resistant latch mechanism is required. The unlacquered bright brass finish develops a natural patina over time and is compatible with doors that see frequent exposure to outdoor conditions. This latch is typically installed by carpenters, general contractors, or experienced door hardware technicians. Its tubular lock format allows for straightforward installation into standard pre-bored door preparations without specialized tooling.
The SDL980U3-UNL fits standard storm door installations in residential settings.

No specific model family compatibility data was provided by the manufacturer for this listing.
Designed as an OEM-style replacement or upgrade latch for standard residential storm doors with a pre-bored tubular lock preparation.
Installation is typically performed by a carpenter or door hardware technician using standard hand tools. Ensure the door is fully closed and stable before disassembling the existing latch mechanism.
