White chain door lock for residential security

The Ultra Hardware 44811 is a keyed chain fastener designed for houses and apartments. It secures the door while still permitting a limited opening for viewing or ventilation. The lock can be unlocked with a key from either side and also opens from inside without a key. Installation is straightforward for a standard door.

White finish with tamper resistant solid

The white coating provides a clean appearance that suits many door styles. A solid metal chain and housing resist forced entry attempts when the lock is engaged. No electronic components or batteries are involved so there is no power draw or operating noise. The mechanical design functions silently during normal use.

Uses Ilco IN8 keyblank for cylinder compatibility

This lock requires an Ilco IN8 keyblank for key cutting or duplication. Buyers who cannot source that specific blank should verify availability before purchasing. The cylinder accepts keys from both interior and exterior sides. No other keyway or key type is supported by this model.

Questions about this item

How is the 44811 chain lock mounted, and what step do installers often miss?

The lock is surface-mounted with supplied screws; the step often missed is pre-drilling pilot holes in the door and frame so the chain bracket aligns without splitting the wood.

What part of the 44811 will need replacement first with regular use?

The Ilco IN8 keyblank or the cylinder pins wear first; a locksmith can re-key or cut a new IN8 key when the original sticks or turns roughly.

What limits how long the 44811 can stay engaged while the door is partly open?

The steel chain length and bracket strength set the limit; holding the door at a wide angle for long periods stresses the chain and can bend the mounting plate.
