An assembly apparatus is for assembling a first member and a second member. The assembly apparatus includes a first gripping section, a second gripping section, and a driving section. The first gripping section includes a contact member and an elastic member. The second gripping section includes a contact member and an elastic member. The driving section drives the first and second gripping sections. The driving section drives the first and second gripping sections such that the contact member of the first gripping section and the contact member of the second gripping section make contact with the second member. The first and second gripping sections grip the second member through the two elastic members urging the respective contact members. The driving section drives the first and second gripping sections such that the first member and the second member are assembled.

A method and apparatus for maintaining a fixed distance between two cabinets during installation are provided. An elongated rail with two stops and two clamps are used. The stops are fixed to the elongated rail with opposing faces placed the fixed distance apart. The assembly is placed between the cabinets and a clamp is used to pinch a cabinet wall of each cabinet against a stop. The cabinets are installed and the apparatus is removed. In some embodiments a second apparatus may be used, one at the top of the cabinets and one at the bottom.
