Abstract
A structural spacer adapted to bridge between two stringers each comprising a web pierced by a pair of slots of predetermined size comprises a steel channel-sectioned body (10) with pressed metal end fittings (11,19) at each end. One end fitting (19) includes two projecting, relatively small hooks (24) with arcuate outer surfaces (25), adapted to respectively engage an edge of the slots. The other end fitting has two relatively larger hooks (14) with arcuate inner surfaces (15) adapted to enter the respective slots and engage over the small hooks of a second spacer engaged therewith. The depths of the large hooks progressively increase from a minimum at their tips, so that when the spacer is swung into the operative position, but not before, the two hooks extending through each slot substantially fill it. An abutment (18) on the end fitting with the larger hooks determines the extent to which the spacer may be swung as aforesaid.
