Outstanding Door Knobs
During the colonial times first door hardware was made out of wood and involved simple latches and strings. Decorative hardware including door knob, appeared after the Centennial Exposition of 1876. Americans first manufactured door knobs. Working of doorknobs is based on a simple mechanism consisting of screw-style axle (called a spindle) that has at least one flat side, which is passed through the door latch, leaving some length exposed on each side of the door to which the knobs are attached. Doorknobs that lose traction can easily be repaired by replacing or adjusting the set screw preventing door knobs from slipping on the spindle. D-doorhandles.com is an online supplier of superb range of decorative door knobs.
