Full Product Description
50mm knotted polyethylene netting is the established industry standard for pheasant release pens, flight pens, and large-scale commercial game bird enclosures across the UK. The mesh size is well proven for containing adult pheasants — providing a secure and stable enclosure structure while maintaining sufficient airflow and visibility through the net. Manufactured in our Fleetwood factory from high tenacity polyethylene using a traditional knotted construction, finished with UV stabilisation as standard for a full outdoor service life.
The knotted construction — using a single English knot at every mesh intersection — gives this netting its characteristic rigidity and strength. Unlike woven or extruded mesh which relies on mesh geometry alone, the knotted joint fixes each intersection permanently, maintaining consistent 50mm openings under the sustained pressure of bird activity and the environmental stresses of year-round outdoor exposure.

Applications
Pheasant Release Pens — the primary application for 50mm knotted PE. Release pens vary widely in scale, from small woodland pens to large commercial operations holding thousands of birds. As a manufacturer we can supply to any dimension — single panels for repairs or the full quantity for a new installation at exactly the width you need, without joining or wastage.
Flight Pens and Drive Pens — covering overhead and perimeter netting on flight pens where adult pheasants are being held and conditioned ahead of the season. The 50mm mesh allows birds to see out and maintains natural behaviour patterns while containing the flock securely.
Commercial Game Management Operations — gamekeepers and shoot managers running commercial operations require reliable, consistent-quality netting at scale. Buying from a manufacturer rather than a distributor means consistent material specification across large orders, direct pricing without reseller margin, and a supplier who can produce repeat orders to the same specification.
Large Flight Aviaries — for larger aviary species including pheasants, peacocks, turkeys, and other large birds, the 50mm mesh provides a practical and cost-effective overhead and perimeter specification.
Vineyard and Orchard Bird Protection — overhead 50mm knotted PE netting is widely used in commercial viticulture and fruit growing to exclude starlings, wood pigeons, and other species during fruiting. The knotted construction withstands the weight loading of heavy fruit clusters pressing against the underside of the net and the repeated tension cycles of installation and removal seasonally.
Hop Yard Training and Bird Protection — used alongside overhead wires in hop yard installations for bird exclusion during the growing season.
Aquaculture Top Nets — for larger freshwater and marine pen systems where the 50mm mesh provides practical bird exclusion coverage. For salmon and trout cage systems where predator netting specifications are more demanding, see our [Aquaculture Netting page] for full cage and anti-predator specifications.
Repairing existing installations
If you are repairing sections of an existing pheasant pen rather than replacing the entire net, we can supply panels to your exact dimensions for patching in. Contact us with the size of the damaged section and your preferred fixing method.
Buying direct from the manufacture
Boris Nets has manufactured netting in Fleetwood since 1958. Every order is produced in our own factory — no intermediary, no reseller margin. For large game management operations requiring substantial quantities across multiple pens, contact us directly for volume pricing. We hold material in stock in Fleetwood and can turn around orders to your specification. Call 01253 874891 or email sales@borisnets.co.uk.
The knotted vs woven difference — why it matters for game management
Woven (Raschel) netting is cheaper to manufacture and widely available, but the diamond mesh structure can deform under load — as birds press against the net face or as the netting is tensioned over a frame, the diamond meshes stretch in one direction and compress in the other. This is not necessarily a problem for light applications but in a game pen carrying thousands of birds through a full season, net shape integrity matters. Knotted netting maintains its square mesh geometry throughout, which means consistent tension across the structure, reliable predator exclusion at the perimeter, and a longer effective service life before replacement is needed.
