On some occasions when using the FL560WS 560mm high Straightcurve Flexline Weathering Steel Edging you may need to shorten a length of edging to meet a length requirement.When this occurs the FL560SLVWS Joining Sleeve is used to connect the two edges squarely. These are fixed with screws through the guide holes in the sleeve to neatly finish.For example this would apply where making rings of custom diameters >1.38m or when making other closed shapes
