Scope note:

Devices or appliances for expanding a material making it taut, removing wrinkles, or the like; used especially with reference to frames upon which canvas or other textile is stretched for painting, having mitered corners that can be forced apart by wedges or keys. For frames that support canvas or other textile and do not have expandable corners, use "strainers (framing and mounting equipment)."
