#461 CEILING HANGER INSERTS
Heckmann Technical Guide
SIZE: 3/16" (4.763mm) round galvanized wire loop with a 26 gage mill-galvanized shell. The wire loop is 1-1/2" (38.1mm) high with 3-5/8" (92.08mm) spread, and the hanger opening of the loop inside the shell is 5/8" (15.875mm) wide x 3/8" (9.525mm) high. The shell is 1-3/4" (44.45mm) wide at the ends, 2-3/4" (69.85mm) long and 11/16" (17.463mm) high in the center.
APPLICATION: Used for hanging suspended ceilings, duct work, plumbing, light fixtures, etc. in new construction. The wire loop is inserted into the shell, and the shell is nailed to the concrete form. When the form is removed, the loop is exposed to receive the hanging fixtures. The clearance for hanging is 5/8" (15.875mm) wide x 3/8" (9.525mm) high. Install as needed.
TEST CONDITIONS: Each sample was cast into a concrete form 9-1/4" (234.95mm) x 9-1/4" (234/95mm) x 3-1/4" (82.55mm) deep. Concrete mixture was Portland Cement Type I at a 3-1 ratio allowed to set over 28 days. Samples were tested to failure at a crosshead speed of 0.5"/minute (12.7mm/minute).
| TEST RESULTS | NO. INSERTS TESTED | AVERAGE PULLOUT |
| 3 | 1,905 lbs |
Insert 1: Load increased to 2,100 lbs, then the rear leg of the insert cracked the surface of the concrete and pulled out of the concrete. No damage was apparent to the hanger at this point. The load dropped to 515 lbs, then began an increase to 790 lbs. At this point, the front leg failed approximately 1/4" (6.35mm) below the concrete surface. The rest of the leg remained in the concrete.
Insert 2: Load increased to 1,905 lbs., then the entire block of concrete cracked into two halves.
Insert 3: Load increased to 1,710 lbs. Failure was the same as #1. Load decreased to 300 lbs. as the rear leg pulled out. Load increased to 825 lbs; then the front leg failed.
