A rigid, glass fiber airduct for conveying an airstream has an interior surface, adapted to be in contact with the airstream, which is coated with a polymeric coating comprising an organic or inorganic biocide. The polymeric coating has a dry solids content between 10 and 20 grams per square foot of duct board surface and retains its abrasion strength and puncture resistance whereby the interior surface of the airduct can be cleaned by conventional industrial or commercial cleaning procedures while in service without exposing glass fibers to the airstream.

Glass fiber airduct with coated interior surface containing a biocide

A batting practice device includes a base which may be secured to a chain-link fence without the use of tools, an adjustable-length rigid arm fixed to the base and extending generally perpendicularly thereto, and a tethered free-swinging ball supported from an end of the rigid arm opposite the base. The base includes a primary support bar configured to slip between adjacent wire portions of the chain-link fence and to securely hook-on thereto, and a stabilizing crossbar generally perpendicular to the primary support bar. The rigid arm includes a first arm member rigidly fixed to the base, and a second arm member that telescopes with respect to the first arm member for the purpose of adjusting the length of the rigid arm. The ball is attached to a reinforced line which extends through the second end of the rigid arm. The length of the reinforced line is adjustable, and extends from the second end of the rigid arm centrally therethrough to the base.
