Abstract: The adjustable bulkhead comprises a pair of vertically disposed and horizontally spaced angle members which are supported on a plurality of vertically spaced tie bars which extend horizontally between the ends of a pair of spaced-apart concrete forms. An elongated channel member is selectively horizontally adjustably mounted on each of the channel members. The lateral adjustability of the channels with respect to the angles permits a bulkhead to be formed between the ends of the concrete forms irrespective of the varying distances between the forms.
