3 – part recessed access covers combine three standard size covers in a single run. They are used when a single part cover does not offer a large enough clear opening or when continuous access is required.
Common applications include grease traps/ arrestors, access to underground stormwater/sewer systems, electricity and communications enclosures where access along the entire run is needed. All covers can be removed for full uninterrupted access or single covers can provide access to specific areas. Systems are available to suit 550, 1000 and 2000 litre grease traps.
These systems are designed and manufactured in full compliance with the requirements of AS 3996 Metal Access Covers and Grates
Decorative edging will add 12mm or 40mm to overall height to allow for tiles or brick pavers
Undercut/drawcut overlap seals and supports the covers at the join without the need for crossbars
‘T’ Frame for class B & C, and cellular frames for class D & G are machined to fit cover precisely.
Frame fits around both covers without the need for additional support; the undercut/drawcut profile supports covers across the middle
Provided widths and loading are the same any standard covers can be combined to create 3 – part units
* Decorative Brass (BE) or Stainless Steel (SS) edging can be added - just specify BE or SS and height (12mm or 40mm)
after part no.
** Optional locking bolts are available for security or back pressure applications - specify standard bolts (LD) or Barri bolts
(BB) after part no.
Note. Rhinocast access covers can be lifted with an AS3996 lifting key
