Polar Bear Interior Handrail Bracket End Assembly Universal series with curved design for added safety. Use as a handrail end bracket for your application. Each round rod and bracket is securely secured with screws to the bracket and the wall base (such as the base column, etc.) The screw hole is "long hole" so you can tilt the screws to the stud (thin column used to attach the wall between the blind/column). The cover can also be easily removed with a flathead screwdriver. Size indicates the width of the corresponding log bar. Please choose the size that fits your round rod. Because the drawings are a common drawing, measurements of both 1.4 inch (35 mm) and 1.3 inch (32 mm) are included. Please be careful not to make any mistakes.
