DIMENSIONS
| PRODUCT DESCRIPTION | PRODUCT CODE | WIDTH | THICKNESS | STANDARD ROLL LENGTH | WEIGHT/lm |
| Polyurethane lagging 12mm | ELA-PU-PLN-N-12V | 249mm-251mm | 12.2mm-13.2mm | 9.7m | 4.21kg |
| Polyurethane lagging 20mm | ELA-PU-PLN-N-20V | 249mm-251mm | 20.2mm-21.2mm | 9.7m | 6.90kg |
Product code for different lengths: Add 5 digit number indicating length in mm.
| Example: | 12 mm 9.7m roll product code: ELA-PU-PLN-N-12V-09700 |
| 20 mm 1.2m strip product code: ELA-PU-PLN-N-20V-01200 |
For strips always allow 100 mm extra length over the pulley face width to have 50 mm at each end of overhang.
Thickness variation (all strips/pulley) +/-0.5mm
Polyurethane lagging with thickness > 15mm only recommended for pulleys with diameters over 400mm.
