    The D250XL Bar Lock XL-Series Coupler is a Type 2, rebar coupler used to connect two pieces of rebar. It consists of a thick walled tube, specially designed lock shear bolts, serrated grip rails, and a center stop pin. The D250XL is made from USA melted and rolled steel.
    The D250XL Bar Lock XL-Series Coupler is used to provide a continuous path of mechanical reinforcing from two pieces of the same diameter rebar

    INSTALLATION

    1. Insert the end of the first rebar halfway into the coupler until it contacts the center stop pin.

    2. Holding the first rebar in place, tighten all the bolts on that half until they are hand tight against the rebar.

    3. Insert the end of the second rebar halfway into the coupler until it contacts the center stop pin.

    4. Holding the second rebar in place, tighten all the bolts on that half until they are hand tight against the rebar.

    5. In a random alternating pattern, tighten all bolts to approximately 50% of the specified bolt torque value

    6. In a random alternating pattern, tighten all bolts to approximately 75% of the specified bolt torque value.

    7. In a random alternating pattern, tighten all bolts until all the heads of the bolts shear off.

    8. Prior to bolt tightening, the serrated rails MUST remain aligned in the same position as they were manufactured. If they are damaged or knocked out of alignment while positioning, installation MUST cease and a new coupler used.

    9. Bolt tightening MUST be done in a random alternating pattern similar to tightening the lug nuts on an automobile wheel.

    10. A high quality 1" pneumatic drive impact wrench,with at least 100 psig air flow and 185 CFM of delivered air through a no less than 0.75" hose MUST be used for installation.
