A cordless electric device has a main body portion extending along an axis and a handle portion extending at an obtuse angle with respect to the axis, the handle portion receiving therein along a second axis a battery pack. The device has a two-part housing, with the parts respectively defining the front and rear of the body and handle portions. The front housing part has latching shoulders respectively disposed on the opposite sides thereof, with each defining a first latching surface disposed substantially parallel to the first axis, while the battery pack has two identical latching members respectively disposed on opposite sides thereof and each resiliently displaceable between latching and release positions, each latching member having two second latching surfaces thereon in a V-shaped configuration, so that one of said second latching surfaces on each of said latching members is disposed substantially parallel to the first axis for engagement with the first latching surface of the corresponding latching shoulder to latch the battery back in place on the device. The latching members are interchangeable and molding of the forward housing part is facilitated.

An optical toe/track measurement system includes a pair of toe gauge assemblies respectively mountable on the two wheels at one end of a motor vehicle and a pair of track scale assemblies respectively mountable on the other two wheels of the vehicle. Each toe gauge assembly includes an elongated tubular housing having toe and track projection systems for respectively projecting toe and track light beams from the opposite ends of the housing, the track beam being projected coaxially with the housing onto the track scale on the same side of the vehicle, while the toe beam is projected perpendicular to the longitudinal axis of the housing onto a scale carried by the toe gauge assembly on the other side of the vehicle. Light is supplied respectively to the two toe gauge assemblies throught two fiber optic cables from a single remote light source. Each fiber optic cable has an input end which plugs into a receptacle in the source enclosure and a bifurcated output end which is optically coupled to both of the projection systems in the associated toe gauge assembly.
