An adjustable transition coupler for coupling armored cable (AC) or metal clad cable (MC), the AC/MC having an outer sheath in a range of outer diameters, to either electrical metallic tubing (EMT) or rigid conduit, the transition coupler comprising:
- a body with a hollow cylindrical section and an extension member attached to the hollow cylindrical section, the hollow cylindrical section having a slot dimensioned to allow passage of a stop plate, a first threaded bore passing through the hollow cylindrical section for receipt of an adjustment screw, at least a second threaded bore for receipt of a screw so as to secure EMT/rigid conduit in a cavity of the hollow cylindrical section, and a pair of holes spaced apart from each other;
- the extension member comprising a first flange with threaded bores formed therein, a curved section attached to the flange at one end of the curved section, and a second flange attached to the curved section at a second end of the curved section, the second flange having a slot formed therethrough;
- an insulator having a hollow cylindrical bushing at one end dimensioned to be inserted into the cavity of the hollow cylindrical section, the cylindrical bushing with at least a pair of snap tabs protruding radially outward and spaced apart from each other so as to snap into one of the pair of holes in the hollow cylindrical section when the insulator is inserted into the cavity of the hollow cylindrical section, a curved member extending to a second end of the insulator, and a stop plate extending radially outward from the curved member at said second end of the insulator, the stop plate dimensioned for passage in said slot of the body, the stop plate movable by the adjustment screw between a minimum deflection and a maximum deflection, the stop plate configured to stop the AC/MC from passage into the hollow cylindrical section of the body when the AC/MC is positioned in the extension member of the body;
- wherein the hollow cylindrical bushing of the insulator is configured to stop the EMT or rigid conduit positioned in the hollow cylindrical section of the body from passage into the extension member;
- and
- a strap having a flange with slots formed therein, each slot dimensioned to allow passage of a screw for threaded engagement with one of the threaded bores formed in the first flange of the extension member, a curved section having a first end attached to the strap flange, the curved section complementary to the curved section of the extension member, and a strap adjustment member attached to a second end of the strap curved section, the strap adjustment member having a plurality of fingers extending therefrom, the fingers arranged in pairs, each pair of fingers dimensioned so as to be able to pass through the slot of the second flange of the extension member so as to prevent the strap adjustment member from disengaging from said slot, wherein the curved section of the extension member and the curved section of the strap are configured to secure the AC/MC cable, where the AC/MC outer sheath may have different outer diameter sizes in said range of outer diameters.
