If you’re looking for an access frame that’s not a standard size then Kimberley’s versatile access frames are what you need. You can create up to 21 different sizes by purchasing only the lengths you need as they can be purchased in any combination. They are designed for simplicity and ease of use with a mitred locking system that includes tapered joining pieces. No gluing is required.
Kimberley’s versatile access frames are made from hi-impact plastic construction and can be painted if needed. They are great for skylight openings and access to plumbing or electrical fittings. Kimberley’s are soon to release larger box quantities in flat pack format, making them easier and more efficient to ship than standard manhole frames.
Lengths available are: (Joist Centres in mm) 350, 450, 600, 750, 900 & 1050
