Before You Begin
Verify your glass and substrate:
- Glass: Tempered or laminated, 12 mm or 13.52 mm thickness. Edges must be polished or flat-ground. Mock-up the layout before drilling.
- Substrate: Reinforced concrete (25 MPa minimum) or pressure-treated wood structural lumber (2"x6" minimum). Soft substrates require an embedded steel plate.
- Tools required: Torque wrench (40-50 N.m), 4 mm hex driver, level (1 m minimum), drill with appropriate bits, marking pencil, painter's tape.
Step 1 — Layout
Position spigots at maximum 1.2 m centers (4 ft) measured between center-of-base. End spigots should be 100-150 mm from the glass edge. Mark all mounting points with painter's tape and pencil.
For installations exceeding 1.5 m glass panel width, calculate load requirements per IBC 1607.8 (750 N/m linear) to confirm spigot spacing is adequate.
Step 2 — Drilling
For concrete:
- Drill the marked points to 90 mm depth using a 12 mm masonry bit
- Vacuum or blow out drill dust completely
- Insert M10 wedge anchors (supplied) flush with substrate
For wood:
- Pilot-drill the marked points to 60 mm depth using a 6 mm wood bit
- No anchor required, direct lag screw installation
Step 3 — Spigot Installation
- Place the spigot base over the mounting points
- Verify level in both axes
- Hand-thread the M10 bolts (or supplied lag screws) into the anchors or pilot holes
- Torque to 35 N.m for the initial pass — do not over-tighten
- Once all spigots are seated, return for final torque to 50 N.m
- Verify alignment with a string line across the spigot tops
Step 4 — Glass Installation
- Apply the supplied rubber gaskets to the inside of each spigot clamp
- Lower the glass panel into the spigot clamps
- Use shims (1-2 mm) to position the glass at the desired height
- Insert the side gasket between glass and clamp wedge
- Tighten the spigot side bolt using the 4 mm hex driver until firm pressure is felt (typically 8-10 N.m). Do not over-tighten — over-torque can crack tempered glass.
- Verify glass is plumb in both axes
- Remove shims if desired (the spigot clamping action will hold the glass in position)
Step 5 — Final Inspection
- Check torque on all bolts
- Confirm 3-6 mm gap between glass panels (for thermal expansion)
- Wipe down the spigots with a soft cloth and stainless steel cleaner
- Save the test certificates and installation records for warranty claims
Maintenance
- Rinse spigots with fresh water every 3-6 months in coastal or pool environments
- Use only non-abrasive stainless steel cleaners
- Inspect bolts annually and re-torque if necessary
- Do not use steel wool, abrasive pads, or chloride bleach on the finish
