Classic rapstraps are used as a replacement for conventional cable ties in many situations, and are especially suitable for tying delicate or deformable items. Amongst other applications, they are extensively used for installing high-performance cabling systems, for securing outdoor banners, and for safely packaging floral bouquets.
A prototype self-releasing tree tie based on the Classic rapstrap design. The inherent elasticity cushions the tree in windy conditions to help strengthen the stem. A secondary band then slowly retracts as the tree grows, ultimately releasing the tie.
10-series Classics are produced in the UK from a premium soft polyurethane resin, and are available ex-stock. The slightly larger 11-series is specifically designed to utilise renewable materials. (These are currently made to order and MOQs may apply.)
The Classic design has proven quite versatile, and over the years we have also developed several bespoke versions of the Classic, particularly for tree tying projects. These have included post-mountable heavy-duty versions, and a fully self-releasing design that expands as the tree grows (and eventually comes undone after a few years).
Even larger & longer straps have occasionally been made for special applications, some them going up to 30 feet long! These "special editions" include a super heavy-duty Classic produced for a National Grid project, and a camouflage-green version that was subsequently repurposed for set dressing on a Tom Cruise movie.
Classic polyurethane rapstraps can be made in a variety of colours, with black, natural and green being the stock colours.
1030-SPU: Soft Polyurethane Classic
Our standard 10mm x 300mm rapstraps are made from a premium 90A durometer polyurethane elastomer.
This material provides both flexibility and strength, and allows the straps to stretch to over 450mm whilst maintaining up to 12kg of loop strength.
1030-SPU rapstraps are supplied in convenient tear-off sheets of 6. They are available in trade bags of 48, and bulk boxes of 6000 straps (unpacked).
Standard colours are black, green and natural. Other colours may be available subject to MOQs.
A slightly longer rapstrap Classic with a more compact cell design. By making the cells 1mm wider and 1mm shorter, we have increased the elasticity to over 100%.
1137-SPU: Extra-Stretchy Classic
This is a slightly longer version of the Classic design with a more compact cell spacing. It will stretch to over 800mm.
It offers all the same benefits as the stock 1030 version, but was designed to provide an increased amount of elasticity. Depending on the exact choice of material, these straps can now stretch by over 100% and provide ties of up to 800mm in length.
1137-SPU rapstraps are supplied in tear-off sheets. They are available in trade bags of 100 and in boxes of 2500 straps (25 bags).
Standard colours are black, green and natural; Other colours may be available on request subject to minimum order quantities.
Classic rapstraps are now available in a 43% renewable-resource material. This BIO43 version required a modified design to increase the elasticity.
1137-BIO43: Renewable Resource Classic
A semi-elasticated Classic rapstrap made from a polyester compound that contains 43% biobased carbon (ISO 16620).
This renewable-resource polymer is not quite as stretchy as our standard polyurethanes, but by implementing a more compact cell spacing, we have been able to produce a rapstrap that still offers a useful amount of elasticity and strength.
The material meets ambient temperature home compostability standards (per EN 13432) up to 27µm thickness. However, please note that larger items (such as this rapstrap) will take much longer to decompose under similar conditions.
BIO43 rapstrap Classics are suitable for many general-purpose applications, although some deterioration of mechanical properties may occur after prolonged outdoor exposure.more
1137-BIO43 rapstrap Classics are supplied in trade bags of 100 straps and boxes of 2500 straps (25 bags). They are currently only available in white.more
Due to the degradable nature of this material, these rapstraps are currently made to order.
Elasticated
Stretches by up to 100%.
Our Classic cellular design is optimised for elasticity. This makes it safer for tying softer items, or objects that can deform or move.
Versatile
Allows for more flexible tying.
With rapstraps you can form multiple interconnected ties. This allows you to quickly bundle, combine & organise in more creative ways.
Waste-Free
Provides more ties per strap.
Rapstrap is self-terminating, so unlike conventional ties, any remaining portions of rapstrap can be easily removed and used for more ties.
Safer
Rapstrap leaves no sharp edges.
The use of a soft polyurethane means rapstrap does not leave dangerous barbs when cut.
1. Rapstrap Classic is supplied in convenient tear-off sheets. To separate the straps, start at the tongue end and pull the straps firmly downwards.
2. When fitting, create the largest possible loop by threading the tongue through a cell at the opposite far end. (Tip: Leave a few cells if removal is required later.)
3. Pull the strap all the way through itself and tighten around the target. Because rapstrap Classic is elasticated it can be tensioned as required.
4. Now remove the end portion and repeat the process. (Note: cut through the second cell after the latch.)
5. The off-cut becomes a new rapstrap that can be used again & again. Each strap can therefore provide several ties with minimum wastage.
6. If you need to release a rapstrap Classic, do not cut off the tongue portion. Instead, reverse-thread the strap back through the same cell, and pull all the way back through to release it.
