DIMENSIONS
| PRODUCT DESCRIPTION | PRODUCT CODE | WIDTH | THICKNESS | STANDARD ROLL LENGTH | WEIGHT/lm |
| Polyurethane lagging 12mm | ELA-PU-PLN-N-12 | 249mm-251mm | 11mm-12mm | 58.2m | 3.70kg |
| Polyurethane lagging 20mm | ELA-PU-PLN-N-20 | 249mm-251mm | 19mm-20mm | 35.0m | 6.39kg |
Product code for different lengths: Add 5 digit number indicating length in mm.
| Example: | 12 mm 58.2m roll product code: ELA-PU-PLN-N-12-58200 |
| 15 mm 1.2m strip product code: ELA-PU-PLN-N-20-01200 |
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.
