To make sure Views Balcony Bar will work, we require the two measurements below. Click here for a visual guide  1. Railing Width. Our unique bracket system adjusts to fit railings that are between 1.75" to 6.25" wide. Our brackets will need to stabilize against two vertical posts. Measure the distance between two vertical balcony posts, starting from the middle of each post. The following measurements will work:  Our 4ft bar will work with a distance that is 46.5" or less.  Our 5ft bar will work with a distance that is 58.5" or less.The Bar Top dimensions are as follows: 5ft Bar top: 60” L x 12” W x 5.5” H 4ft Bar top: 49” L x 12” W x 5.5” H
