Luma 2 heavy-duty wall or ceiling mounted projection screen. Includes the AutoReturn Roller. An attractive, practical choice wherever a large spring-roller screen is required. Simple in design and rugged in construction. Constructed entirely of heavy gauge components for years of dependable operation. The AutoReturn Spring Roller includes a built-in inertia reduction mechanism. With AutoReturn the screen unrolls in the conventional manner, then slowly and gently retracts to the closed position on its own after a simple tug on the handle. Screen surface retracts slowly and smoothly into the case, slowing even more as it approaches its upper limit. Intermediate stop positions allow you to lower or raise the screen completely, or stop at any point in between. Prevents potential damage to the dowel or screen surface through repeated impact with the case.
