Abstract
The invention provides a tape measure housing having resilient material located at its outersurface. The resilient material defines one or more gas-filled cavities, each of which is located on a line tangential to an outer wall of the housing between the outer wall of the housing and an outer wall of the resilient material. This provides improved shock protection.
