Three construction types

There are three extension methods, provided that existing table legs are fixed to the table frame or table top in a stable and wobble-free manner:

1. Identical extensions

The most elegant method preferred by most table owners is the application of an identical leg piece , This assumes that either spare parts are available or the condition and shape can be implemented with new workpieces. The extensions are secured by hanger bolts whose counter-threads are mounted on the undersides of the existing legs. Hollow metal feet are only suitable if a filling allows this attachment method. Ring 2. Ring or Belled Shims

The relatively least expensive type of extension is the attachment of rings or clamps. The components are usually fixed with holding screws leading from the outside to the inside and can be mounted in a few minutes without drilling. To increase the stability of the rings or clamps may be a filling on which the existing Tischbeinfuß is placed. Visually, these extensions lead to widened table legs.

3. Sideways rails

Visually most noticeable are rails that fix an extension element. The principle is similar to the splints of broken arm or leg bones. By placing the rail on the inside of the table legs, the visual effect can be almost hidden. The joining of the new and old components is possible by screwing, gluing or wrapping.

Solid or hollow table legs

Hollow table legs, usually made of metal, allow an "insertion" of an extension. If the existing table feet are fixed and not visibly connected to the extension pieces, an auxiliary construction in the cavity is required. Special clamping blocks with internal threads allow the screwing of extensions with hanger bolts.

Massive table legs, mostly made of wood, are directly adaptable to the extension method. So-called T-grooves can be hammered into the undersides of the table legs after a hole. For rectangular table leg shapes, the thread of the hanger bolts may need to be adjusted to close gaps or gaps between the table leg and the extension piece.

Center of gravity and table statics

While the stability of a table is hardly influenced when shortening table legs, except for the uniformity of the lengths, the table statics changes with extensions. The heavier a tabletop or the construction of the upper third, the more likely a Standerhöhung lead to instability.

Tips & TricksFor orientation, you can assume that the stability and stability change from extensions of about ten percent. Also note that prolonged leverage increases the force on connections such as fittings or glued surfaces.
