As a compact and clean rope end termination, the splice has a long tradition in tree care. The patented SPLY is extremely compact, as the diameter of the rope is not increased at any point and even in the splice eye only minimally. This means that the splice can easily be pulled through all common SRT and DdRT devices, eliminating the need to pull the entire rope through the device.
At the same time, the splice has an extra safety feature, because part of the core is pulled through the entire eye. (Particularly thin eye splices have no core threads in the splice eye. This means an increased safety risk if the sheath is damaged.)
