Abstract: A curtain wall has a plurality of hollow, extruded vertical and horizontal members. The members have a pair of spaced retainer walls which engage a shear block with a pair of tabs that twist locks onto the retainer walls before fastening the block to the member. A second member slips over the block and is fastened by screws. The abutment of the tabs limits rotation of the block and attached member, providing support for a glazing panel attached to the members. The members have longitudinal recesses accommodating wiring that may be covered with a cover. A bracket interacting with the retainer walls like a shear block may also be used.
