Abstract: A roller-shutter door system comprises a pair of opposed substantially parallel guide rails and a door formed by longitudinally hinged door slats coupled to a retraction roller. The door can be opened and closed with rotation of the retraction roller, and longitudinal ends of the door slats ride within door guide channels in the guide rails. Exterior side seals may cover a gap between the door slats and the door guide channels, and wear shields may be interposed between coated exterior surfaces of the door slats and the side seals so that the side seals bear on the wear shields instead of the coated exterior surfaces. The guide rails may have equipment channels on interior sides thereof, and radius guides may be releasably received in open superior ends of the equipment channels. The radius guides have outwardly facing guide surfaces to guide the door slats toward the retraction roller.

Abstract: A carpet installation tool capable of being used to crease and tuck carpets in a wide variety of locations, including those difficult to access. The tool includes a handle that defines a longitudinal axis of the tool and a head disposed at one end of the handle. The handle has a longitudinal length sufficient to accommodate at least one hand of a user. The head has a neck portion adjacent the handle, a heel portion adjacent the neck portion, and a toe portion adjacent the heel portion. The neck portion extends at an acute angle to the longitudinal axis of the tool, and has a length sufficient to accommodate a hand of the user. The heel portion is adjacent the neck portion so that a heel edge defined thereby is offset from the longitudinal axis of the tool in a direction transverse to the longitudinal axis. The heel and toe portions define a distal edge that extends in a direction transverse to the longitudinal axis of the tool.
