Claims1
Railing construction comprising in combination,
- a baluster having a pair of opposed internal vertical wall surfaces and an internal horizontal wall surface extending therebetween defining a recess at its upper end,
- a banister positioned within said recess in surfacial abutment with said vertical and horizontal wall surfaces,
- said baluster and said banister defining bores in axial alignment with one another when the banister is supported in place within said baluster recess, said baluster also defining a pair of inwardly directed counterbores,
- a fastener assembly within said bores and including a head and a nut element one each disposed within a baluster counterbore, said nut element including baluster engaging prongs and permanently in place within the baluster, and
- said fastener assembly biasing said baluster vertical wall surfaces into engagement with said banister with loads imparted to the railing banister being transferred directly to the baluster via abutting banister and baluster surfaces whereby shear loading of the fastener assembly is avoided.
