Test.
SIZE: 8" (203.2mm) Long x 1-3/8" (34.92mm) wide between 1/2" (12.7mm) inside flanges, with one slot 9/16" (14.28mm) x 5-1/2" (139.7mm) long. Tests were performed on 11 gage and 16 gage slots in plain steel conforming to ASTM A-569.
APPLICATION: Slots are welded to steel columns and beams usually every 16" (406.4mm) vertically. Anchors are installed into the slots with a 5-1/2" (139.7mm) vertical adjustment.
TEST CONDITIONS: Four samples each of 11 gage and 16 gage slots were welded to a 3/8" (9.525mm) x 4-1/2" (114.3mm) x 9" (228.6mm) steel plate. The weld bead was 1-1/2" (38.1mm) long on each of the top two corners and the bottom two corners. #134 Corrugated Channel Slot Anchors 16 gage x 1-1/4" (31.75mm) wide x 3-1/2" (88.9mm) long from the face of the channel were used for the test. The anchors were installed in the center of the channel and were pulled out at a 90° angle to the slot. The samples were tested to failure at a crosshead speed of 0.5"/minute (12.7mm/minute).

11 Gage Slots
Anchor 1: The anchor T-tail bent upward approximately 70°; then the
ears folded downward causing the anchor to pull out of the slot. Maximum load 920 lbs. No
damage to the slot.
Anchor 2: Same failure as #1. Maximum load 862.5 lbs. No damage to slot.
Anchor 3: Same failure as #1. Maximum load 1,072.5 lbs. Neck area on the anchor was
slightly wider than the others which could account for the higher value and the slight
upward distortion on one side of the channel slot.
Anchor 4: Same failure as #1. Maximum load 945 lbs. No damage to slot.
16 Gage Slots
Anchor 1: Same failure as 11 gage #1. Maximum load 630 lbs. Upward
distortion on both sides of the channel.
Anchor 2: Same failure (anchor & slot) as #1. Maximum load 625 lbs.
Anchor 3: Same failure (anchor & slot) as #1. Maximum load 732.5 lbs.
Anchor 4: same failure (anchor & slot) as #1. Maximum load 687.5 lbs.
