The all new In deck Downunder roller - Dual lid and split hinge roller with precision bearing
2 pcs lid with dual roller system below deck.
For pools over 5m wide and 12m long. Deflection is too great and you need to split the roller and downunder lid.
This is achieve by a shared centre and lid joiner assembly. With precision bearings for ease of use.
Deflection happens when the blanket weight is too great for the roller, gearing and brackets. The roller will bend and the gearing will pull off 90 degrees. Which will fail over time.
By splitting the roller and lid, you have 2 smaller lids and rollers to work with and a shorter roller width will not bend with the weight.
The outcome is that the system will last a long period of time with very little wear.
