Abstract
A conduit strap (10) is disclosed for installing a conduit (12) through an aperture (16) in a metal stud (14). The strap (10) will secure the conduit (12) in place without the use of any fasteners. The strap is installed by inserting a arm (26) through the aperture in the metal stud and then rotating the strap so that a portion of another arm (20) pass through the aperture and engages the back side of the stud to tightly secure the strap within the stud.
Claims4
A strap for bracing conduit passing through a rectangular hole in a metal stud, comprising:
- (a) a generally rectangular sheet of flexible material, adapted to fit within the hole in the metal stud, and having a top edge, a right edge, a bottom edge, a left edge, a front face, and a back face;
- (b) the top edge having a slot dividing it into a top-right tab and a top-left tab;
- the top-right tab running in a direction coincident with the top edge;
- the slot running in a direction approximately perpendicular to the top edge;
- the top-left tab running from the slot downwards at an angle to the left edge, the tab having its uppermost portion bent in a backwards direction such that a permanent displacement exists between the top-right tab and the top-left tab viewed in the plane of the sheet;
- (c) the right edge having a slot dividing it into a right-upper tab and a right-lower tab;
- the right-upper tab running in a direction coincident with the right edge;
- the slot running in a direction approximately perpendicular to the right edge;
- the right-lower tab running in a direction parallel with the right edge, the tab having its rightmost portion bent in a backwards direction such that a permanent displacement exists between the right-upper tab and the right-lower tab when viewed in the plane of the sheet;
- (d) the bottom edge having an indentation dividing it into bottom-right tab and bottom-left tab;
- the bottom-right tab and bottom-left tab running in a direction coincident with the bottom edge;
- the indentation having a width greater then the diameter of the conduit to be braced, the indentation tapering smoothly inwards and having a semicircular upper boundary such that the overall depth of the indention is greater than the diameter of the conduit to be supported.
- (e) the left edge having a slot dividing it into a left-upper tab and a left-lower tab;
- the left-upper tab running in a direction parallel with the left edge, the tab having its leftmost portion bent in a backwards direction such that a permanent displacement exists between the left-upper tab and the left-lower tab when viewed in the plane of the sheet;
- the slot running in a direction approximately perpendicular to the left edge;
- the left-lower tab running in a direction parallel with the left edge, the tab having its leftmost portion bent in a backwards direction such that a permanent displacement exists between the right-upper tab and the right-lower tab when viewed in the plane of the sheet.

A method of installing a conduit strap in a metal stud to secure a conduit, the metal stud having a rectangular aperture therethrough, comprising the steps of:
- positioning the conduit strap at a predetermined angle to its final position, the conduit strap including a resilient plate formed of first, second, third and fourth arms, a first notch being formed between the first and second arms on a first side of the plate and a second notch formed in the plate between the third and fourth arms on the plate on second side of the plate;
- positioning the strap over the conduit passing through the aperture in the metal stud and inserting a lip of the fourth arm through the aperture to bear against the back side of the metal stud with an edge of the aperture entering the notch between the third and fourth arms of the strap;
- rotating the strap relative to the metal stud so that a lip formed on the first arm of the strap will pass through the aperture to bear against the back side of the stud, the arms of the strap being deformed as the strap is rotated into the engaged position to tightly engage the strap within the aperture of the metal stud.
