Joint, for wooden handrails

  • The handrail system with balls

    The handrail system with balls is suitable for designing

    • wooden handrails
    • wooden handrails with stainless steel ball joints
    • stainless steel handrails with stainless steel ball joints
    • combined handrails made from stainless steel and wood, connected with stainless steel ball joints

    The special features of the system are stainless steel ball joints that make handrail installation easy, particularly on stairways, and the "aluminium core" of the wooden handrails that stabilises the handrails and increases their bending strength. Suitable stainless steel ball ends round off the appearance of the handrail system with balls.

    The wooden handrails are made from high-quality solid wood, and the surface is coated with a highly resistant 2-component PUR lacquer.

    Stainless steel ball joints

    The stainless steel ball joint of the system opens up new design options. It is the flexible connecting element for wooden and stainless steel handrails or a combination of both.

    Connected handrails can now be continuously aligned by 90–270° in any direction.

    The stainless steel ball joint is quick and easy to adjust, and is therefore even adaptable to seemingly complicated wall and stairway layouts.

     

    The secret of the "aluminium core”

    Handrails made from wood are equipped with an aluminium tube as a core insert, the so-called "aluminium core".

    The "aluminium core" stabilises the handrail and prevents distortion. The additional bending strength allows greater distances between the handrail brackets.

    An internal thread is cut into the aluminium tube. Bends, straight sections and connection pieces can be incorporated with a perfect fit.

     

    Easy to install

    Attaching wooden handrails to each other or to wooden bend elements is even easier using plastic or brass stud bolts. They are screwed into the threads of the “aluminium core” at both ends. The "aluminium core" and the stud bolts therefore provide the individual components with a secure seating.

    In order to cover cutting edges, the stainless steel length connectors are inserted between the wooden handrail elements.

    Mounting wooden handrails

     

    Stainless steel roses connect the wooden handrail and the stainless steel ball joint or ball end to each other firmly in a positive-fitting way. They are installed between the stainless steel ball joints or ball ends and the wooden handrails.

    The stainless steel ball joints are fitted to the stainless steel handrails using coupling joints.

    A pre-milled guide groove makes installation and linear positioning of the handrail brackets on the wooden handrail easier.

  • Ball handrail system planning

    Planning of individual components

    Proceed as follows when planning your handrail system with balls:

    • Work out handrail routing on wall, measure and draw layout
    • Plan handrail system with all individual components
    • Take required distance from the wall and dimensions of the individual components into consideration
    • Enter required handrail lengths and individual components in a part list
    • Include about 1.5 handrail brackets per running metre
    • Include handrail brackets before and after direction changes
    • Pay attention to fixed direction specifications of the curves;
    • Stainless steel ball joints can be used universally

  • General installation reference for handrail system with balls

    The following points must be observed during the installation of handrail systems:

    • Take the required distance from the wall into consideration when cutting the handrails to size. The distance from the wall and the installation dimensions of the individual components determine the length of the handrail.
    • Re-measure after each directional change, since even extremely small tolerances mount up.
    • For optimum safety, ensure that the handrail is securely attached to the wall.
    • Observe wall plug manufacturer's processing references
    • Be sure to adhere to the legal requirements for railing construction.

    Mounting wooden handrails

    • Cut wooden handrails to size with a clean right-angled cut (with fine-toothed mitre saw)
    • Cut internal thread at both ends of handrail with a thread-cutting tap M10 x 0.75 mm (be sure to use cutting oil!)
    • For installation with wooden curves, screw plastic or brass connecting screws into internal threads
    • Apply wood glue to cut surfaces
    • Tighten wooden curves and align
    • Sand and re-lacquer transitions
    • Alternatively, use length connectors to cover the cutting edges. In this case a brass screw must be used as the connecting element.

    Installing stainless steel handrails

    • Cut stainless steel handrails to size with a clean right-angled cut (with suitable mitre saw)
    • Push coupling joint for stainless steel ball joint or ball end as far as it will go into handrail at both ends (joint-tight)
    • Tighten screws with Allen key (4 mm)
    • Fit ball cup

    Mounting stainless steel ball joint and ball end on wooden handrails

    • To install the stainless steel ball joint to wooden handrails, fit stainless steel roses to both ends of the handrail
    • Screw stainless steel ball joint slightly into internal thread of handrail ends, align and tighten
    • To install the stainless steel ball end to wooden handrails, screw brass connecting screw into ball end
    • Then screw ball end into internal thread in handrail end and tighten
    • Apply wood glue to cut surfaces of wooden hemispherical ball end
    • Push hemispherical ball end firmly onto end of handrail; secure with adhesive tape if necessary.

    Installation of stainless steel ball joint and ball end on stainless steel handrails

    • When mounting stainless steel handrails, install a stainless steel ball joint whenever a direction change occurs
    • Screw stainless steel ball joint into coupling joint until it is firmly seated and joint-tight
    • Continue turning until the ball is freely movable again after a "click"
    • Note: The ball cannot be removed again in this state
    • To install the stainless steel ball end to stainless steel handrails, screw brass connecting screw into stainless steel ball end
    • Then screw stainless steel ball end into coupling joint as described above

    Mounting handrail brackets to the wall

    Handrail brackets are wall mounted as follows:

    • Mark drilling points for wall mounting the handrail brackets and drill holes
    • Select fixing material (wall plugs, screws) in accordance with the type of wall
    • Screw handrail brackets to wall

    Notes for installing stainless steel handrail brackets:

    Stainless steel must not be used in conjunction with normal steel. No tools must be used that have been previously used to process iron or steel.

    Mounting handrail brackets to the wall

    Adjustable handrail brackets are recommended for uneven walls. Inaccuracies and differences can be re-adjusted for with adjustable handrail brackets within the range of ±4 mm (height) and max. 10 mm (depth).
