What is the maximum gap between glass pool fence panels?

Editor: View Mate All Glass Railing

The absolute maximum gap between glass pool fence panels or between panels and end posts must not exceed 100mm (4 inches), as stipulated by international safety codes (ASTM F2286, IBC 1607.7).

This is a non-negotiable safety threshold designed to prevent child entrapment or access.

Key Regulations & Best Practices:

1.100mm Sphere Test:

Authorities employ a 100mm-diameter sphere to test gaps. If the sphere passes through any opening, the fence fails inspection.

This applies to gaps between panels, beneath the bottom rail, and at gate/wall junctions.

2.Ideal Gap Target:

Professionals aim for a gap of ≤80mm (3.15 inches) to account for hardware settling, thermal expansion, or structural movement.

Consequences of Non-Compliance:

a).Child safety risk: Gaps >larger than 100mm allow toddlers to squeeze through.

b).Legal liability: Non-compliance violates pool barrier laws (e.g., IBC, AS 1926.1), potentially voiding insurance coverage.

c).Structural weakness: Excessive gaps increase panel deflection under wind loads.

Hardware Impact:

Use adjustable 316 stainless steel clamps/spigots to maintain consistent gaps during installation and as the hardware settles.
