A budget-minded way to put a matching matte black knob on six interior doors at once, tested to a real cycle count, with a small compatibility catch on older door frames worth checking first.

A straightforward exterior handleset for anyone building their own lock and handle combination rather than buying an all-in-one kit, provided a deadbolt is sourced separately.
