ABSTRACT:
A plug adapted to be inserted into the open end of a channel of a concrete slab which is provided with a plug portion having a perimeter conforming to the cross section of the channel and of smaller diameter than the cross section of the channel, the plug being provided with outwardly extending fingers from the perimeter of the plug portion which are adapted to engage the surfaces of the channel, the fingers having arms extending therefrom which support a ring adapted to abut the exterior surface of the slab about the channel to accurately position the plug within the channel. The plug permits water to drain from the channels through slots between adjacent fingers and facilitates the use of mortar for joining the ends of adjacent slabs or the like.
