英国采购需求：安全带、攀岩安全带、工作定位安全带、提升带、拖车带、攀岩网

I'm interested in finding out if you manufacture self-retracting fall arrest blocks that can be attached to harnesses, specifically with a length of 15 meters. I am looking for more details on your product offerings, including specifications, safety features, and any applicable certifications. Additionally, could you provide information on pricing, minimum order quantities, and lead times for delivery? Understanding your production capabilities and options available would help us in making a decision. Looking forward to your prompt response.
