What Does D525-54 Mean? The D525-54 is a larger-capacity high-lift drum designed for applications requiring up to approximately 54 inches of vertical high lift before the garage door transitions into the horizontal track. Its larger 5-1/4" drum profile and 500 lb per-drum rating make it suitable for heavier doors than smaller D400-series high-lift drums.
High-Lift Systems Only: The D525-54 is designed for compatible high-lift track configurations. It should not be substituted for a D400-96, D400-144, standard-lift drum, vertical-lift drum, or another high-lift drum simply because the shaft diameter matches.
Cross-Reference: D525-54 may also be referenced as Canimex D525-54HL, APCO 5250-54, DNS 54, or OMI 2500. Always compare the full specifications rather than relying only on a cross-reference number.
Confirm Before Ordering: Verify the existing drum model, amount of high lift, door height, door weight, cable diameter, cable length, 1" keyed torsion shaft, and track configuration before selecting replacement drums.
Sold as a Matched Pair: This listing includes both the left-hand and right-hand D525-54 drums so both sides of the garage door use the same groove profile, diameter, and lifting characteristics.
Safety: High-lift cable drums, lift cables, and torsion springs operate under substantial tension. Spring tension must be completely released before loosening or removing cable drums. Proper drum selection is critical to cable travel and door balance; professional installation is strongly recommended.
