A recoiler for rolling shutter assemblies that includes a protective cover that reduces the risk of accidentally releasing the strap and, consequently, the shutter curtain. The protective cover is disposed over the locking mechanism to prevent the inadvertent unlocking of the mechanism either by intentionally forcing the mechanism to the unlocked position or the accidentally engaging the mechanism with another object. Additionally, the recoiler facilitates adjustment of the tension in the torsion spring of the take-up roll without the necessity of removing the take-up roll assembly from the strap recoiler housing. The recoiler provides access to the shaft so that a torque may be applied to rotate the shaft to increase and/or decrease the tension in the torsion spring. |
