FAQ
What keyway options are available for the LD-376 lockset?
The LD-376 supports both SC1 (Schlage) and KW1 (Kwikset) keyway profiles, allowing you to match the common keying standard in your target market. Each lockset comes with 3 brass keys, and we can provide keyed-alike or master keyed configurations on request for multi-unit projects.
Is this lockset suitable for exterior entrance doors?
Yes, the LD-376 is designed for entrance door applications and carries an ANSI/BHMA Grade 3 residential security rating. The brass and steel construction provides good durability, though we recommend using a deadbolt in conjunction with this knob lockset for maximum exterior door security.
What is the difference between the brass and steel knob versions?
The brass knob version offers a warmer, more traditional appearance and natural corrosion resistance, making it ideal for classic and vintage-style interiors. The steel knob version provides exceptional strength and durability at a more economical price point, making it popular for high-volume residential and multi-unit projects. Both versions use the same internal mechanism and security features.
Can I mix different finishes in a single order?
Yes, mixed orders with multiple finish options are fully supported. As long as the total order quantity meets our 200-set MOQ, you can combine any of our nine available finishes. This is particularly useful for wholesale distributors and hardware stores that need to stock a variety of options for their retail customers.
