Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang PRIME-LINE dari 3G Electric.
What load ratings are available for PRIME-LINE garage door cables?
PRIME-LINE spring cables and extension cables are rated for maximum loads of 2,155 lb and 1,385 lb respectively, as specified for the carbon steel models. These ratings apply to the cable assembly, not the door weight alone, and should be matched to the total door system weight including hardware. Always verify that the cable's load rating exceeds the door's operating weight by a safety margin per local codes.
Are PRIME-LINE T-handles and L-handles interchangeable with existing garage door lock mechanisms?
PRIME-LINE keyed T-handles (e.g., GD 52169) and L-handles (e.g., GD 52123) are designed as direct replacements for common residential garage door lock assemblies. The T-handle has a 4-inch arm length, and both types use standard keyed locking cylinders. Check the backset and hole pattern of your existing lock before ordering; these handles typically fit doors with a 7/8-inch to 1-inch thickness and standard 2-3/8-inch or 2-3/4-inch backset.
What is the difference between a PRIME-LINE spring cable and an extension cable?
PRIME-LINE spring cables (e.g., GD 52102) are designed for use with torsion spring systems, where the cable winds around a drum and is attached to the bottom bracket. Extension cables (e.g., GD 52263) are used with extension spring systems, running from the spring to the track or header. Both are made from carbon steel, but the spring cable has a higher load rating (2,155 lb) compared to the extension cable (1,385 lb). The overall length is 8 21/32 ft for both, supplied as a pair.
Can PRIME-LINE slide locks be used on sliding garage doors?
Yes, PRIME-LINE slide locks (e.g., GD 52118) are specifically designed for bolting onto sliding garage doors. The lock has an overall depth of 3 3/16 inches, a base length of 3 1/8 inches, and a base width of 5/16 inches. It uses a bolting mechanism to secure the door in the closed position. Ensure the door's track and frame can accommodate these dimensions before installation.
What material is the PRIME-LINE garage stop ball made from?
The PRIME-LINE garage stop ball (GD 52286) is constructed from rubber and includes a retracting cord. It is used as a buffer or stop for garage doors during operation, preventing over-travel. The rubber material provides impact absorption and durability for repeated use. This part is not load-bearing but serves as a mechanical stop in the door's travel path.
