Fall – the slight angle of a cement block or slab needed for drainage

FC – Fibre cement board, 25mm+ thick used typically under tiles as flooring on a deck

Footholds – any object that a child could use to climb on which may aid an attempt to breach a pool fence line or barrier

Frameless – a glass fence barrier system where the panels are supported from the bottom by spigots or pin fix stand-offs. No posts are used

Friction plate – the insert in a spigot which is tightened to safely clamp the glass panel

Galvanized – A protective zinc coating applied to steel or iron to protect from rusting. Can also apply to steel fasteners such as nails or screws

Gate latch – A fitting to hold the gate in place when closed

Glass-to-glass – term for identifying method of fixing for hinges, posts and glass panels – see also 'wall-to-wall'. Also 'glass-to-round' (post)

Grade-A safety glass – glass which has been toughened or laminated to

Grout / structural grout – Epirez is TGD’s recommended non-shrink structural grout for the setting of core-drilled spigots. Other brands include Sika, B&L and Tiflex but may not perform as well over time or be as pourable

Handrail – either a top-mounted section or side-mounted bar with standoffs. Mandatory in some conditions

H4 Timber – Timber which is treated for safe use inground and is protected against termites, borers and severe decay

INOX – an abbreviation of 'inoxydable', the French word for 'stainless'

Insertion rubber – the rubber channel section which fits between handrail lengths and the top of a glass panel

Pre-cast concrete steps – Concrete blocks cast into slab steps. Not suitable for mounting glass panels on due to their inadequate thickness

Pin fix – also called ‘side-mount’ or ‘stand-off’ – glass panels mounted over the edge of a floor or staircase by use of circular pins which fit through holes in the glass
