An impact-absorbing end cap for an instrument such as a level is provided that is secured to an end of the level and has an outer portion and an intermediate portion. The intermediate portion is positioned between the outer portion and the body of the level and is securely fastened to the outer portion. In addition, the intermediate portion provides greater resilient compressibility than the outer portion so that the end cap is better adapted to absorb impacts to the outer portion and thereby prevent damage to the level. Preferably, the outer portion has a profile matching the body profile at the end of the level and the intermediate portion forms a serrated intermediate profile to facilitate compression of the end cap. Also preferred is where the end cap includes an inner portion with less resilient compressibility than the intermediate portion.
