Notes

BS EN 124 and CD 534 apply to products with a clear opening up to 1 metre. The Hercules range of access covers have a clear opening greater than this, however load capability and design features exceed the requirements of these documents. Please note that Hercules 1,200 x 1,200mm cover is the only cover in the range to have keyholes for manual lifting. All values stated are nominal within 2.5% tolerance.
