Substitute check before you accept a different core
bowling ball custom
Spec Check for bowling ball custom orders asks which specification choices remain open and what must be verified before you accept an alternative. Duty rating, dimensions, power and documents still apply as a method: here duty is house versus custom cycle, dimensions are weight and diameter, power is usually not applicable, and documents are the quoted-model sheet rather than a company brochure. We do not certify USBC compliance; we ask the factory for the document that names the quoted model. Input voltage and NEMA plug checks are unused on undrilled balls; do not invent electrical fields.
Request Factory QuotesHouse vs custom cycle
Commercial-duty house polyester versus a one-off custom reactive piece. If the quote swaps polyester for reactive resin to hit a number, record the swap as a substitute.
Pounds and grit
Weight in pounds and surface grit or polish must sit on the priced line. A 14 lb request answered as 15 lb mixed is not the same configuration. User weight capacity language belongs only on youth or house mixes that use it.
Quoted-model sheet
Request the current sheet for the quoted core and coverstock. A company ISO poster or an association membership page does not stand in for the model file.
Open choices that split a bowling ball custom column
Core geometry
Named symmetric, asymmetric or pancake must match the brief. A core omitted or swapped without a written change is a new proposal. Selectorized versus plate-loaded language belongs to gym machines; the analogue here is house polyester versus custom reactive.
Coverstock resin
Polyester, urethane or reactive resin named on the sheet. Photo-only answers stay off the comparison. Home-rated novelty spheres and commercial-duty house polyester are not interchangeable without a written duty check.
Layout and origin
Factory-undrilled or a stated layout with pin-to-CG notes. Silent drilling that later appears as an extra splits the quote. US or other origin is written as its own line if requested, not used as a quality slogan. Return to inquiry options when the form name is still open.
Keep substitutes in a second column
Send the open bowling ball custom choices
Spec Check keeps bowling ball custom substitutes in their own column until you accept the change. FREE sourcing support and up to 3% remain capped and are confirmed only after we review the open specification, quantity, destination and sourcing requirements for qualified business buyers.
