A shelving connector has symmetrical arms for locking insertion into metal shelving. The shelving and the connector preferably include radiused surfaces for safety and attractive appearance. The radiused edges of the metal shelving serve a dual function of stiffening the shelving and providing a receiver for arms projecting from the connector. The connector preferably has resilient tabs which are captured in apertures in the receivers. The connector can be advantageously formed from injection molded ABS plastic.

Metal shelving connector and kit

An improved industrial chair having a mechanism for adjusting the position of a support column in relation to a fixed platform, such as a chair base portion. The chair comprises a support column having an exterior surface with a plurality of engaging surfaces arranged along the length of the column for selectively engaging portions of a coupling. The coupling is shaped for selectively engaging the support column and positioning the support column relative to the fixed platform. The coupling has an inner surface shaped for contacting the support column engaging surfaces in a substantially matched shape friction fit, and the coupling further has an adjustable circumference structure for permitting selection between locking engagement and relative movement between the support column and the coupling. The chair further has structure suitable for operably retaining the coupling in fixed relation to the support platform.
