This invention relates to a lengthy flexible strap of plastic material which can be used to support heating and cooling ducts in a building structure. The strap has a series of multiple spaced-apart apertures extending throughout its length to facilitate mounting and remounting of such ducts into desired final permanent arrangement. The grouped multiple apertures in the strap have both large and small adjacent locations with lines of severance therebetween for passage of large fastener heads through the larger apertures and prevention of such larger fastener heads through the smaller apertures. The strap may be easily relocated on the fasteners for realignment of the supported ducts.
