PRIME-LINE E 28317 Mortise Style Fluted Glass Door Knobs for Replacing Broken Antique Lock Sets on Interior Doors

If your door knob set is acting up or broken, the E 28317 Mortise style fluted glass door knob set is the perfect choice for updating and fixing hardware on interior doors. With a beautiful and classic fluted glass and classic bronze finish, it's the perfect choice for your antique or vintage interior doors. Installation is a breeze, and the glass door knob set features 2-inch outside diameter knobs.

These door knobs are for interior use only and include a 17/64-inch x 3-1/2-inch steel spindle with 3/8-inch -20 threads. This classic style door knob set fits square drive spindle systems commonly found in antique and vintage door hardware sets, and it can adjust to accommodate different door thicknesses. The diecast base on these knobs include the set screws for fastening the knobs to the square spindle, but it does NOT include any of the following components, which must be purchased separately: the internal mortise lock body, the door rosettes, the trim and strike plates, or the latch and fasteners.

For matching rosettes and latch, see Prime-Line's model numbers E 2543. Note: This item cannot be used on pre-bored doors that have large, newer style door knob holes without first prepping them to receive this hardware. To ensure a solid surface for the rosette fasteners, the large 2-1/8-inch (approximate size) holes must first be filled with a hardening filler, such as Fix-It-All or Bondo Body Filler, taking care to avoid damaging any pre-finished door surfaces during application and finishing.

It is also recommended to apply a small amount of Loctite ThreadLocker 271 to the set screw threads in the event they become loose.

In summary, the E 28317 fluted glass door knob set is the ideal choice for replacing or updating interior door hardware, with its beautiful classic design and ease of installation. However, it is important to exercise caution when handling the glass knobs, as they can crack or break if subjected to impact, and broken glass can cause serious cuts. If the knob cracks or becomes loose, it should be replaced immediately, and children should be advised not to hang from the knobs.
