Abstract
A rattle-free rail construction includes a plurality of vertical line posts, each having an H cross-sectional configuration defining vertical channels in the post. Each channel includes a pair of opposed, vertically extending arcuate grooves which are of the correct diameter to properly accept self-tapping screws. Another pair of opposed, vertically extending retention grooves are disposed in each channel, parallel and adjacent to the arcuate grooves. Horizontal bars of the railing construction are secured with the ends thereof in opposed channels of adjacent line posts, the bars being spaced apart in each channel by post inserts which snappingly engage the retention grooves in the channel. Double-sided foam tape is applied to the top and bottom ends of the horizontal bars, and the entire assembly is secured in a channel by joining a top subrail onto top of post by means of screws received into the top openings of the arcuate grooves.
