<p>A balustrade unit is disclosed which has a pair of spaced-apart channel-section members, the mouths of which are directed towards each other. The free edges of each channel-section member are bent so as to form a pair of longitudinally-extending flanges, and a pair of longitudinally-extending, spaced-apart engaging elements are provided on and upstanding from the base portion of each channel-section member. A plurality of balusters are disposable between the channel-section members, each baluster having, adjacent each end thereof, a transverse slot, the two slots in each baluster being parallel and in register with each other and the ends of the balusters being receivable between the engaging elements when the balusters are in position between the channel-section members. There is a plurality of spacers each one of which is extendable between adjacent balusters of the balustrade unit, each spacer having a table portion the side edges of which are receivable in rebates in the longitudinally-extending flanges, and a pair of valances disposed normal to the table portion and adapted to irremovably engage with the engaging elements when the spacer is disposed between adjacent balusters. Each table portion includes a bight, the base of which is receivable in a said transverse slot and the limbs of which extend on either side of the baluster to enclose the space between the baluster and longitudinallyextending flange.</p> |
