Abstract: A power tool battery pack enclosure is configured to be coupled to battery pack receptacles of a plurality of power tools, each battery pack receptacle configured to removably receive a plurality of power tool battery packs. The enclosure includes a first clamshell member and a second clamshell member configured to be coupled around at least a portion of an exterior surface of each battery pack receptacle. Each of the first and second clamshell members have a top wall portion configured to be received over the exterior surface of the battery pack receptacle and a sidewall portion that extends downward from the top wall portion over at least a portion of the battery pack housing when the battery pack is received in the battery pack receptacle.

Abstract: A storage system (10) incorporates protective shelving (24) of improved construction. The protective shelving (24) includes a semi-rigid overlay (50) covering the top surface and front edges of a rigid undercore (48). The overlay (50) includes a rounded front edge, and raised ribs and alternate grooves extending continuously between the front and rear ends for more strength, resilience and impact resistance.

Abstract: An interchangeable shelf support bracket (10) particularly for use with either one of two different thicknesses of shelves includes a side plate (12), mounting pins (14), edge flange (16), and pair of opposing retainer tabs (22, 24) each of which includes a lip (b 26, 28) adapted to receive the edge of one of the two shelves.

Abstract: A modular system (30) for framing and supporting work surfaces and storage units includes a pair of generally rectangular end frames (32) having side member (36) each defining inside and outside channel sections. The end frames (32) are releasably secured together by lateral connectors (34) which are adjustably clamped along the inside channel portions of the end frame side members (36). The lateral connectors (34) are adapted for supporting storage units by means of inverted J-shaped hooks 70. The work surfaces are independently supported on arms (84) which are adjustably clamped along the outside channel sections of the end frame side members (36) in order to facilitate rearrangement and adjustment in accordance with the requirements of laboratories and the like. A modular system (120) adapted for use with existing structural walls (128) is also disclosed.
