Our bungee cords and tension straps maintain perfect tension on your printed banners: ratchet straps, spring tensioners, stainless steel turnbuckles. They prevent wind flapping that rapidly damages banners at attachment points.
A properly tensioned banner lasts 2-5 years outdoors. Poorly tensioned banners tear within months at the eyelets. Investing in quality tension straps pays for itself quickly.

For large tarpaulins requiring high tension, metal ratchet tensioners.
For permanent installations and corrosive environments (seaside), marine stainless steel turnbuckles.
The choice depends on the load and the frequency of handling. The elastic bungee cord (6 to 10 mm EPDM rubber cord with PVC or metal hooks) absorbs gusts and prevents flapping in the wind: ideal for advertising tarpaulins, banners and light covers up to 25-30 kg of traction. The ratchet tensioner with polyester strap (25 to 50 mm) delivers several hundred kilos and is suitable for securing heavy loads on trailers. For a durably stretched mesh tarpaulin, choose the stainless steel turnbuckle. The bungee cord remains the quickest and most economical solution outdoors.
The capacity of an elastic tensioner depends on the diameter of the rubber cord. A 6 mm EPDM bungee cord offers a restoring force of approximately 8-12 kg, an 8 mm cord reaches 15-20 kg and a 10 mm reinforced model exceeds 25-30 kg. The useful elasticity represents 80 to 100% of the initial length: a 40 cm stretcher stretches up to 70-80 cm. The galvanized metal or stainless steel hook is the weak link: check its breaking load, often limited to 20-40 kg. To maintain a tarpaulin or cover, multiply the attachment points every 30-50 cm rather than overloading a single tensioner.
Yes, provided you choose the right materials. The EPDM rubber cord is durably resistant to UV, ozone and temperature variations from -30 to +80°C, where a natural rubber bungee hardens and cracks in one season. For the hooks, A2/A4 stainless steel does not rust, ideal by the sea; hot-dip galvanized steel offers a good compromise, PVC hooks prevent corrosion but limit the load. For permanent exterior fixing of tarpaulins, covers or nets, combine braided textile sheath and stainless steel ends to guarantee 3 to 5 years without degradation.
The price of an elastic tensioner depends on the diameter, length and type of hook. A short EPDM bungee cord (20-30 cm) with PVC hooks costs around €0.40 to €1, an 8-10 mm model with stainless steel hooks costs €2-4 per unit. The elastic cord by the meter (reel of 25, 50 or 100 m) costs 0.30-0.80 €/m and allows you to create custom-made tensioners with separate hooks, the most economical solution for large construction sites. Purchased in lots or boxes of 50 to 100 pieces, the unit cost drops by 20 to 40%. For a fleet of tarpaulins, purchasing in bulk quickly amortizes the investment compared to replacing torn tarpaulins.
The standard elastic tensioners with PVC, galvanized metal or stainless steel hooks are kept in stock in the common diameters of 6, 8 and 10 mm, as well as in EPDM rubber cord by the meter on spools of 25 to 100 m. For these references, shipping occurs within 24 to 48 hours and delivery in Europe takes 2 to 4 working days depending on the destination. Bulk orders remain available immediately. For custom tensioners (length, specific crimping, large quantities), allow 1 to 2 weeks. Anticipate your needs before the peak event season.

The tensioners become essential as soon as a tarpaulin, cover or net must be temporarily fixed outdoors and remain taut despite the wind, repeated handling or temperature variations. They equip event stands dismantled every weekend as well as semi-permanent installations at an outdoor point of sale, a market or a warehouse where protective tarpaulins must be adjusted regularly. Choosing the right model depends above all on the load to be maintained and the frequency of assembly and disassembly: daily use on a mobile stand does not impose the same constraints as a fixation installed once for the season. Anticipating these parameters before purchasing avoids undersizing the installation or, conversely, investing in an oversized tension system for a light requirement.
For a lightweight tarpaulin that is frequently dismantled, a double-hook flat tensioner offers quick handling and good tension distribution across the entire width of the tarpaulin. For quick, one-off fixing on a single point, a short model with a single hook is generally sufficient, whereas an installation exposed to sustained gusts requires several distributed tension points rather than a single oversized tensioner. The width and material of the tarpaulin to be attached also influences the choice of model: a thick canvas supports more anchor points than a simple protective cover.
Efficient installation distributes the tension over several points rather than concentrating the effort on a single tensioner pushed to its limit, which reduces the risk of breakage and extends the life of the equipment. The angle of traction also matters: a tensioner pulled perpendicular to the anchor point works more efficiently and wears less quickly than a tensioner pulled at an angle repeatedly. It is also recommended to avoid leaving the material under maximum tension continuously when the installation remains in place for several weeks, as this accelerates the natural relaxation of the material.
Between two events, storing the tensioners relaxed rather than stretched preserves their traction capacity over time, a material kept under permanent tension gradually loses its original elasticity. A quick visual check before each installation makes it possible to spot a deformed hook or cracked material before it breaks during use, which prevents a tarpaulin from coming loose in full exposure or on the public highway. The hook fixing kit is easily replaced piece by piece rather than buying a whole set as soon as an element shows signs of fatigue.
The first mistake is using a single tensioner to hold a large surface area tarp, which concentrates all the tension on a single point and causes a tear at the eyelet. The second is to neglect the necessary length: a tensioner that is too short forces the anchor points and prematurely wears out the hooks, while a model that is too long loses tensioning effectiveness. Finally, mixing tensioners of different strengths on the same installation creates unequal points of weakness, with the tarpaulin relaxing more quickly where traction is weakest. It is better to standardize the set of tensioners used on the same structure to guarantee uniform tension over the entire perimeter.
