Knob Handle variety of materials

Teres DifeoHandles are attachments fixed on access portals such as doors and windows to facilitate pulling open the door or window to effect entry or exit. In many cases, the handle may simply be a knob which is attached to a locking device and helps to also lock the door simultaneously when it is closed. Knobs are essentially different in shape from handles as they are rounded whereas handles are linear in shape. Knobs and handles can be fixed at different points on the door. Some doors have the handle very high up on the door, to ensure that small children cannot access them, while others may have the handle lower down.

In many circumstances, knobs are more difficult to operate, especially for elderly and differently-abled people. They do not provide a firm grip and hence they could be slippery for an elderly person or someone with special needs to operate. In such cases, a lever-functioned handle would be more appropriate.

Some door handles are recessed into the body of the door as in automobile doors. This provides an aesthetically pleasing effect. However for more high-traffic doors, these recessed handles are not recommended, as their spring-lock mechanism may not take much wear and tear. Folding handles are good for balcony-doors and outside windows as they fold back into the frame when not in use.

Knobs and handles come in a variety of materials. Almost all metals can be used but if the knob or handle is to be facing outwards, it needs to be weather resistant, be able to repel rust and corrosion and also provide a good grip when wet. In such cases, highly polished handles may not be suitable, and metal handles may be textured, carved or decoratively embellished to provide some roughness. Brass and bronze knobs and handles provide a classic touch, while plastic handles can look stylish and contemporary.

Knurled or patterned knobs provide a good grip for turning, while lobed knobs are useful for lightweight turning operations. Domed knobs are installed on vertical surfaces and they help water to run off easily when exposed to rain or wet weather. Plastic handles are very effective when there is a need for a tough, non-conducting material which will not rust or corrode or react to aggressive chemicals. Ball-shaped knobs look decorative on drawers and cabinets especially when they’re made of ceramic, painted wood or polished metals. T-shaped knobs are useful in moving levers and gas tanks.

Depending on your specific requirements, you can purchase the correct type of knobs and handles from your local hardware store or order them on-line from manufacturers.In many circumstances, knobs are more difficult to operate, especially for elderly and differently-abled people.
