Handrail tie description.

The handrail tie is a horizontal metal tie that ties the handrail to the adjacent stringer.

This is to prevent lateral movement of the handrail, thereby avoiding loosening of the spindles that may result in an unstable handrail.

Usage.

The handrail tie is designed to stop lateral movement of the handrail.

This will normally be used on flights with a narrow stairwell that is up to about 1′ or 300mm between handrail centres.

With the tighter turns in these flights, the corner allthough giving some stability, often requires additional assistance with keeping the handrail steady over a longer period.

Design.

The ties are a steel bar that has a timber thread on one end and is screwed through the stringer face into the carraige, at a point that crosses with the handrail flow from the lower adjacent flight.

The other end of the bar has a short 90º turn, keeping the return short to fit between the spindles and is then fixed to the underside of the handrail by means of a flat plate mounted on the end of the bar.

The thread is easily achieved by cutting the thread from a coach bolt and welding to the end of the handrail tie.

The bar itself will normally be perfectly adequate at 3/8″ or 9mm Ø. This is just a bit more slender than the 1/2″ or 12mm Ø bar and blends in much nicer.

Once fitted the bar is best finished in a dark colour or painted to match the stringer colour.

Position.

The handrail tie is best positioned with the handrail fixing plate as close to a spindle as possible and on the upper side of the spindle to allow space for a screwdiver and screws while fixing to the handrail.

This is a traditional handrail tie, there are many of these in and around London, they are made using a length of 3/8″ 9mm Ø bar.

At the stringer end, the bar would be annealed and flattened slightly, a hole 3/8″ Ø would be drilled through the stringer into the carriage, then the bar would be hammered home to secure it.

At the handrail end, the bar would be heated till soft enough to bend, then bent through 90º for about 1 3/4″ – 44mm, the bar is then bent back through 90º for about 1/2″ – 12mm heated and penned flat, finally a hole is drilled through the flat section of the bar to allow a fixing screw into the underside of the handrail.

The handrail tie with a plate on both ends may be used when fitting after the handrail is already in place, the plate that attaches to the string is normally rebated into the stinger, filled and painted to look like an original style or pre fitted handrail tie.

This is another option for fitting a handrail tie after the handrail is already fitted, this may give a more stable fixing to the stringer due to the large rose that is screwed to the stringer.
