APPROVALS: The 3/8 inch rod size is Underwriters Laboratories listed and Factory Mutual approved for use with up to 4 inch size pipe while the 1/2 through 3/4 inch rod sizes are listed/approved for use with up to 8 inch size pipe. Complies with Federal Specification WW-H-1 71 E (Type 19) and Manufacturers Standardization Society SP-69 (Type 18).

INSTALLATION:

(1) Nail insert to wooden forms.

(2) Where convenient, reinforcing rods may be placed in the opening through the top of the insert, or short lengths of reinforcing rod may be wired to the insert prior to pouring concrete. However, note that the specified load ratings and approvals are not dependent on the use of any reinforcing rods in contact with the insert.

(3) After concrete is poured and wooden forms are removed, insert screw driver into slot in knockout plate and snap it out.

(4) The nut may be put on the rod before inserting in the insert body. Then, turn rod so that elongated nut lies across the slot; screw rod through nut until rod is firmly against the top of the recess.

- Nut may be put on hanger rod before insertion, avoiding need of locating nut in insert body prior to inserting rod.

- Insert nut, when located in position, wedges against the sloping sides of insert, providing greater support than if resting on lower edge of the insert body.

- Wedge-shaped body is so held by concrete in compression thus increasing load carrying capacity.

- Easily removed knockout plate.

-       Rod can be adjusted along complete length of slot.

- One body for six sizes of rod.
