KNOB SECURE ™ is a product that corrects loose door handles on bi-fold doors.  Most bi-fold doors are constructed with an open space (hollow-core) between the front and back panels.  Knob Secure™ provides a way to have a secure installation of the door knob. The nylon bushing that is available through PLR Solutions, LLC, can be installed within a few minutes by anyone, even someone who feels they have no technical abilities. The installation process will take less than five minutes per door. It requires only the use of a drill motor, drill bit and screwdriver. The current door knob and screw can be reused without modification.

Whether you own or manage real estate, or are a homeowner, the issue of loose bi-fold door knobs in hollow core doors is one of your most annoying and expensive maintenance concerns. The Knob Secure ™ spacer provides a simple solution that will permanently stabilize the loose door knob condition.

Stabilizing the knob is accomplished by creating a compression fit between the end of the spacer, the front door panel and the door knob. Anyone can install the spacer in five minutes using a 1/2” Dia. twist drill bit, drill motor and a screwdriver. The benefit of using the Knob Secure ™ spacer is in the elimination of damage to the door, thereby avoiding future door replacement costs. The damage can be minimized on existing doors and avoided altogether if included in all new bi-fold door installations.

Traditionally only one door knob has been used on most bi-fold doors. However, recently door handles with multiple screws have been used in an attempt to solve the problem without success. The Knob Secure ™ spacer is an effective solution for these applications as well. For example, if using a dummy lever handle with three screws, utilize equal amounts of the Knob Secure ™ spacers and bolts. Install the bolts from the front of the door, through the door handle mounting plate, spacers and the back door panel. Finish by tightening a nut on the bolt and the handle will be permanently secure.

The Knob Secure ™ spacer is the only known solution that will stabilize the loose door knob and eliminate additional door damage while providing flexibility to change door knobs.
