Below are instructions for properly installing a handrail bracket to a stainless steel tube. This requires tapping and drilling the handrail and then attaching the handrail bracket to the handrail. This may require two people. Another way to connect the handrail bracket to the post, is by welding.
NOTE: For cable systems, handrails must be installed before your cable. The handrail and handrail brackets will provide the necessary support for the posts while the cable is being installed.
Caution: Wear protective ANSI approved safety glasses, working gloves and breathing mask at all times
Tools Required (links included)
Drilling and Tapping
- Position handrail on saddles or handrail brackets
- Mark your drilling points with a pen using the posts and saddles as a template
- Remove saddles from post or handrail bracket (in the case it is removable)
- Center punch your marked drilling points; this will keep the drill bit from skidding
- Adjust the drill press to 620 rpm
- Apply cutting oil; drill the tube at your marked points using Cobalt drill bits. [For round tube only: you will need a self-centering drill press jig
- Tap the tube using the hand-powered drill (at low speed) and the corresponding tap
- Repeat steps 4-7 to all your marked points
