A lower intermediate plate (81) having a first (75) and a second (77) surface is positioned between the slide block (80) and the lower crossbar (46). The first surface (75) is in contact with the slide block (80) and the second surface is in contact with the lower crossbar (46). At least the first surface (75) of the lower intermediate plate (81) has a smooth, low-friction surface to facilitate sliding of the lower horizontal cross member (28) with respect to the lower crossbar (46). Also disclosed is a retainer (22) for securing a lift truck attachment (20) to a lift truck carriage. The retainer (22) includes a retainer plate (56) having a hook (58) on one end that is slideably positioned on the attachment. The hook (58) is disposed to engage the carriage of the lift truck (10). An opening (90) is positioned in the retainer plate (56). A block (118) is movably secured to the attachment. The block (118) is disposed to be positioned in the opening in the retainer plate (56) to maintain the retainer plate (56) in a desired position with respect to the carriage of the lift truck (10).
