Masonite 6 Panel Molded Door (Textured)

The Masonite 6 Panel Molded Door delivers professional-grade precision with its 1/4” trim allowances and choice between hollow core (20-30 lbs) or solid core (60-90 lbs) construction. Worth it for contractors who need exact specifications for warranty compliance and customers who understand the massive sound insulation difference between core options.

Skip it if you’re looking for a budget slab to butcher on site. Those 1/4” trim limits from the bottom rail and sides aren’t suggestions — exceed them and you’ve voided the warranty. Buy a cheaper door if you need more trimming flexibility.

Trim Specifications and Lock Block Details

Maximum trim allowance stands at 1/4” from the bottom rail only for height adjustment and 1/4” from each side for width. That’s your working room. Not an inch. Not half an inch. A quarter inch.

The 14” lock block provides legitimate flexibility for lockset placement and security upgrades. Most contractors appreciate this detail — it means you’re not hunting for the sweet spot or worrying about drilling into dead air. The block runs tall enough to accommodate standard locksets plus deadbolts without gymnastics.

Trim Specification	Maximum Allowance
Height (bottom rail only)	1/4 inch
Width (each side)	1/4 inch
Lock Block Length	14 inches

These aren’t arbitrary numbers. Masonite engineered these doors with specific structural limits. Trim beyond the allowances and you’re into the structural components that hold everything together. The warranty limitations specifically call out that trimming beyond allowances voids coverage.

Core Options Drive Performance

Hollow core runs 20-30 pounds with minimal sound barrier while solid core (Safe ‘N Sound) weighs 60-90 pounds with superior sound dampening. That’s a 40-60 pound difference you feel immediately during installation.

The weight tells the story. Hollow core provides minimal sound barrier — you’ll hear conversations through it. Fine for closets and pantries. Terrible for bedrooms next to living areas or home offices. Solid core delivers superior sound dampening and more resistance to impacts. It also feels substantial when it swings — none of that hollow door rattle.

Montana’s temperature swings make solid core worth considering for exterior-facing interior doors. That extra mass buffers against temperature differentials better than hollow construction. Not an exterior door — but for that interior door leading to an unheated garage or mudroom, solid core makes sense.

Warranty coverage reflects the quality difference: 1-year limited on hollow core versus 5-year limited on solid core Safe ‘N Sound. Masonite backs their solid core product five times longer. That’s confidence in materials.

Available Dimensions and Applications

Standard widths run from 24” to 36” in 80” height. 84” and 96” heights also available for those custom applications or taller openings. Thickness typically measures 1-3/8 inches for interior doors; 1-3/4 inches available for some applications.

The 24” width works for tight spaces — pantries, water heater closets, mechanical rooms. The 36” handles wheelchair accessibility requirements. Everything in between covers standard residential applications. That 96” height option matters in Montana’s custom home market where 9-foot and 10-foot ceilings show up regularly.

Width Range	Height Options	Typical Applications
24” - 36”	80”	Standard residential
24” - 36”	84”	7-foot openings
24” - 36”	96”	Tall custom openings

Hardware compatibility includes standard 3-1/2” hinges and 2-3/8” or 2-3/4” backset locksets with pre-bored options available. Fits standard interior door jambs with pre-hung options available separately. Nothing exotic here — your standard hardware works fine.

Certifications and Compliance

These doors feature FSC-certified manufacturing facility availability and SCS Global Services Recycled Content certification. CARB compliant with low VOC emissions in no added urea formaldehyde models.

Montana builders working on LEED projects or green-certified homes care about these certifications. The FSC option particularly matters in a state where forest management stays politically charged. Low VOC matters for tight homes with mechanical ventilation — you’re not off-gassing formaldehyde into a controlled air environment.

FAQ

Can the door be trimmed more than 1/4” if needed?

No. Maximum trim allowance is 1/4” from bottom rail only for height and 1/4” from each side for width. Exceeding these limits voids the warranty. Buy a different size door if you need more adjustment.

What’s the real difference between hollow and solid core?

Weight runs 20-30 lbs for hollow versus 60-90 lbs for solid. Hollow provides minimal sound barrier while solid delivers superior sound dampening. Solid core also resists impacts better and provides a higher quality feel. Warranty coverage is 1 year for hollow core versus 5 years for solid core.

Do these doors come pre-finished?

Doors come primed white, ready to paint or stain. Warranty requirements state doors must be finished/painted on all 6 sides immediately. That means top, bottom, both faces, and both edges.

What about fire ratings?

Fire rating available according to manufacturer specifications. Contact your supplier for specific fire-rated options and documentation.

What tools are needed for installation?

Required tools include drill, screwdriver, level, chisel, saw for minor trimming, and safety glasses. Standard door installation toolkit — nothing specialized required.
