Abstract

An improved boot structure for protecting the extensible member and the adjacent end of a telescopically reciprocal mechanism from contamination. The boot structure includes an elongated convoluted body formed of elastomeric material with an integral band on one end thereof in which a special split-ring device is contained. The split-ring device is provided with air passages which allow the boot to breathe as it expands and contracts in response to similar movements of the telescopically reciprocal mechanism, and is configured to demountably attach the one end of the boot structure to the housing of the telescopically reciprocal mechanism.
