Stopped the spoilage at the top
We used to lose the top foot of the clamp to birds and weather every year. First winter with the Covertec cover and the face was clean right to the top.

Heavy-duty woven covers that shield your silage film from weather, birds, rodents and wildlife. A secure seal means less spoilage at the top of the clamp and more feed in front of stock.
Each cover is woven from robust HDPE monofilament yarn at 220g/m², with high UV stability so it keeps protecting the film through long spells of outdoor exposure. Reinforced seams and hems take the strain, while holding loops and a slip-resistant finish make it quicker to position and keep in place. Available in six standard sizes to suit clamps, pits and heap configurations.

The problem
Damaged film at the top of the clamp is wasted feed.
Birds, rodents and the weather all work away at the silage sheet. Once the film is punctured, air and water get in, the top layer heats and spoils, and you are throwing away feed you have already paid to grow and ensile. A protection cover takes the punishment so the film underneath keeps its seal.
What it is
A dense woven shield over your silage film.
Each cover is woven from robust HDPE monofilament yarn at 220g/m², built to take weather and wildlife year after year. The dense weave and high UV stability mean it keeps protecting the film through long spells of outdoor exposure.

What it does

Right size, well made
Ordered the 10m by 15m and it covers the clamp with plenty of overhang. Heavy material, well finished, and the loops make it easy to pull over with two of us.

Tough cover, quick service
Arrived quickly and well packaged. Feels far heavier duty than the net we had before. Knocked a star only because delivery arrived a day late.

Common questions
Silage Clamp Covers questions, answered plainly
No. It goes over the top of your silage film to protect it. The film makes the seal, and the cover stops birds, rodents and the weather damaging it, so that seal lasts.
The dense woven construction is built to resist birds, rodents and wildlife getting at the film underneath, which is where most top-of-clamp spoilage starts.
Six standard sizes: 5m × 7m, 8m × 7m, 10m × 12m, 10m × 15m, 12m × 15m and 15m × 18m. Pick the size that covers your clamp with enough overhang to weight down the edges. Not sure? Send us your figures and we will confirm the right one.
The material is highly UV stable and carries our 10-year guarantee. Store and install it correctly between seasons and it is built for a long service life.
