The Husky 655 Plus is the premium wood model — the most popular Husky stair for new construction and replacement, with meaningfully wider treads, heavier stringer construction, and heavy-duty double section hinges compared to the entry-level 444.

1×6 kiln-dried SYP treads — the most noticeable upgrade from the Model 444 is the tread width; a 1×6 tread is substantially wider and more comfortable underfoot than a 1×4 tread, providing a more secure and stable step for users carrying items to and from the attic

1×5 stringers and 1×6 frame — the heavier stringer and frame construction of the 655 Plus provides greater overall rigidity and load-bearing capacity; the larger lumber dimensions throughout make the 655 Plus noticeably more solid than the 444

Heavy-duty double section hinges — the 655 Plus adds heavy-duty double section hinges at the fold joints between stair sections, providing additional strength and stability at the highest-stress points on the stair structure; this is the key structural upgrade over the 444's single section hinge

Full-width heavy-duty piano hinge — same full-width piano hinge as all Husky models, spanning the entire door/stair width for maximum rigidity and elimination of air leakage at the head of the stair

3/16" steel rod under each tread with large washers — keeps the stair sections rigid under the 375 lb rated load and prevents bending or separation between sections during repeated use

375 lb load rating — 25 lbs higher than the Model 444, reflecting the 655 Plus's heavier construction and more robust hardware throughout

Available in 10' ceiling height — the 655 Plus is the right choice for 10' ceilings, with wider 1×6 treads and heavier construction than the Model 444

All three Husky models are available with energy saving insulation panels and a fire retardant door panel option. Specify at time of order — contact DOORTEC for availability and current pricing.

R3 Insulation Panel

Insulated door panel with weatherstripped frame — R3 thermal value. Reduces air infiltration and heat transfer at the attic opening.

R5 Insulation Panel

Mid-range insulated door panel with weatherstripped frame — R5 thermal value. Improved energy efficiency over the R3 panel.

R10 Insulation Panel

High-performance insulated panel with weatherstripped frame — R10 thermal value. Meets Energy Star Qualified Homes R10 thermal requirement.

Fire Retardant Door Panel

Fire retardant treated door panel. Specified when code or preference requires a fire-resistant attic door panel.

Model 655 Plus Installation in Oklahoma City

The Husky Model 655 Plus is DOORTEC's primary attic stair recommendation for Oklahoma City residential installations — the 1×6 SYP treads, heavier construction, and 375 lb load rating make it the practical specification for most OKC homes where a new or replacement attic stair is being installed. The 655 Plus covers ceiling height of 10'. DOORTEC installs the Model 655 Plus throughout Oklahoma City, Edmond, Norman, Moore, Yukon, Midwest City, Guthrie, El Reno, and the OKC metro.

For Oklahoma City homeowners choosing between the 655 Plus and the aluminum Model 1200, the ceiling height is the primary decision point — if your ceiling is 10', the 655 Plus is the right choice; for 12-foot ceilings, the Model 1200 aluminum is the correct specification. Call (405) 720-7107 to confirm which model fits your home.

Premium Wood Attic Stairs Tulsa & OKC

DOORTEC's Tulsa location serves the greater Tulsa metro with the Husky 655 Plus as the standard attic stair specification. Tulsa's residential market — which spans established mid-century neighborhoods through newer suburban construction with higher ceiling profiles — makes the 655 Plus's 10' ceiling height and premium construction the right fit for the majority of installation opportunities.

For Tulsa homes with ceiling heights above 10', DOORTEC specifies the Model 1200 aluminum. For homes where budget is the primary driver and load rating requirements are modest, the Model 444 is available. Contact DOORTEC at (405) 720-7107 or doortec.com to discuss the right model for your Tulsa home.
