The T-bolts are widely used in the anchoring system and available in a choice of diameters and lengths
for each cast-in channel size
Fixings to cast-in channels are by drop forged T-head bolts, face-entered into the channel after the concrete has set. The projecting bolt has a notch on the end of the shank so that the correct engagement of the T-head in the channel lips can be clearly seen. The allowable load capacity of a fixing depends on the channel type and the anchor spacing and position
