Standard sleeve lengths:
SLV060: 50mm NB 300, 400, 450 & 600mm lengths. Custom lengths available on request.
SLVWEDGE: Standard Wedge zinc plated

Sleeves are designed to be fitted with either a standard wedge, or a security wedge requiring a removal tool, both standard and security wedges allow sleeves to be installed flush at ground level.
Sleeves can be supplied with an M10 tapped hole located 15mm below the sleeve top, to fit either an M10 hex bolt or a Trilobular security set screw. This option is ideal for securing PVC poles and in this instance it’s recommended sleeves are placed 30mm above ground level.
The external shape ensures sleeves will not rotate when set in concrete.
Internal dimensions of all sleeves are designed to be a snug fit with the pole.
Sleeves are fitted with PVC end caps to prevent concrete entering the sleeve during installation.
