<p>A retractable barrier system comprises a support member, for example in the form of a housing (10), a spool (14) supported for rotation by the support member, a spring (34) adapted to apply a biassing load to the spool (14), and a skirt (30) arranged to deflect water away from or around the spring (34) thereby reducing the quantity of water impinging, in use, on the spring (34) and reducing corrosion thereof.</p> |
