FAQ
What is the difference between single cylinder and double cylinder deadbolts?
Single cylinder deadbolts have a keyhole on the exterior and a thumb-turn on the interior for quick exit. Double cylinder deadbolts require a key on both sides, providing extra security but requiring a key for emergency exit. Check local building codes as some jurisdictions restrict double cylinder deadbolts.
How long is the bolt throw on this deadbolt?
The LD-056 is available with 1 inch (25mm) or 1-1/8 inch (29mm) bolt throw options. The 1-1/8 inch throw provides enhanced security and is recommended for exterior doors.
Can this deadbolt be installed on a door with an existing knob lock?
Yes, the LD-056 is designed to be installed above an existing keyed entry or passage knob set. Standard door preparation includes a separate bore hole for the deadbolt approximately 6 to 12 inches above the knob.
Is the double cylinder version compliant with fire safety codes?
Double cylinder deadbolts may not comply with fire safety codes in some jurisdictions because they require a key for exit. Always verify local building and fire safety codes before installing double cylinder deadbolts. Single cylinder versions are universally code-compliant for residential use.
