Handrail Tube Square
TBE.SQU.157.3
Regular price $49.00Stainless Steel Square Tube is usually used as a handrail or top rail for our railing systems. Tubes are available by the foot from 3 feet up to 19.7 feet. They are made from ANSI 316 stainless steel tubing which measures 1.57 x 1.57 with a tube thickness of 0.102" with a stain brushed finish.
*** Lengths over 7 feet need to be shipping LTL. Please contact sales for a Shipping quote ***
Overview
Instructions
- Place duct tape on the clamp of the cut-off saw and to all other areas where the tube will touch the metal in order to protect the surface from getting scratched while being cut
- Mark cutting point, clamp the tubing in place and commence the cut
- Immerse the cut end into water to cool the cut tube
- File any sharp edges evenly with a fine metal file
- Clean the tube using paper towel and some household cleaner
- Note: if necessary, ream/deburr the outside and inside of the tube. Be careful not to scratch the tubing while deburring, keep the deburr tool straight
- To polish the cut, follow instructions for maintaining stainless steel surface
NOTE: A small amount of surface corrosion is not uncommon after a some exposure to weather or salty conditions. We recommend using our passivation solution or some sort of stainless polish to keep any surface corrosion from happening; more information available on our Engineering Specs Page.

Instructions
- Mount the posts to the floor or the brackets to the wall before installing the handrail tube. Please refer to other instructions document found on our website for help in that operation
- Place the handrail tubing on the saddles. Mark the drilling points using a marker
- It’s very important not to skip this point otherwise the drill bit will skid. Remove the handrail then place it on a working table. Mark the drilling points with a center punch. Repeat this several times in the same location to give a good guide for the drill bit.
- Use the corresponding drill bit size shown in table above.
- Apply cutting fluid on the drill bit.
- Hold firm but without pressing too hard the hand-drill then gradually apply pressure to drill through the top rail with stopping a couple of times to reapply the cutting fluid. Complete all marked location.
- Replace the drill bit with the corresponding tap bit shown in table.
- Apply cutting fluid on the tap. Tapping is to be done at a slower speed then drilling. Start at a slow speed then increase the speed once the tap catches a couple of threads.
- Reverse the direction of the drill to remove the tap remembering to carefully keep the tap bit straight.
