Product Details

Enhanced Abrasion resistance UHMWPE pulley cord for Window Channel Balancer

Brand Name SOVETL
Place of Origin China
Material Other, UHMWPE
Type Braided Rope

Product Features

Block and tackle window balances are also known as channel balances. Block and tackle balance systems use an extension spring force to counterbalance the weight of the window sash. The pulley and cord system control the tension in the spring as the sash moves up and down in the frame.

About the Role of cord

In this balance system, the rope acts through friction between the block and  tackle. Therefore, it is necessary to ensure that the rope does not break due to massive back and forth friction movements.


The UHMWPE cord we provide

The use of high-performance fiber UHMWPE as the raw material for Cord will have extremely excellent wear resistance. Moreover, the double braiding method will also increase the fatigue life of the cord in the balance system once again.


How to obtain samples.

Usually, inventory samples can be provided in small quantities for free. However, for customized products, sometimes there are different requirements for the roughness of cords in different window balancing systems (which can lead to different friction forces). We are willing to collaborate with customers to develop and braid cord with different surface roughness to fit your balancing system.
