Each Rectangular type plastic threaded tube insert that we offer has ribs on its exterior to provide a tight fitting at all times, no matter what attachment. These slot in perfectly to provide additional thread attachment where-ever required, these could be adjustable feet or other attachments which hold in excellently at all times. These rectangular threaded tube ends are easily slotted into a tube to provide easy addition for external components, hence their nickname of fixings for feet (or threaded components).
All of our Rectangular Tube Inserts are made from a selection of strong and reliable materials, some of which include LDPE Plastic & Aluminium Alloys. Commonly regarded as finishing or protection products these inserts are often used to cap the end of a Rectangular tube / section, hence their nickname within industry of 'Tube Caps'  due to the internal conservation that they provide. Along with their protection benefits, they are also recommended for functional uses such as installation into a table leg as an easy solution to extend or add height, especially when paired with an adjustable foot. Each of these Rectangular Inserts feature a ribbed shank, this allows it to easily fit a range of wall thicknesses and tube diameters as the ribs easily compress when fitted either by hand or hammer.
