1.5" NPT Extension Column Cross-Reference: Chief, Peerless-AV, Premier & More Mapped to Expert Mounts Equivalents
215 part numbers

1.5" NPT standard
Free fit help
Every ceiling-mount extension column, drop pipe, and telescoping pole on this page shares one connection: a 1.5" NPT thread, the standard used across TV and projector ceiling mounts. That common thread is why an Expert Mounts pipe screws directly into a Chief, Peerless-AV, Premier Mounts, or Crimson AV structure, and why you can replace a discontinued or hard-to-source OEM part without changing anything above the ceiling plate.
This cross-reference maps 215 competitor part numbers across 18 brands - including Chief, Peerless-AV, Premier Mounts, Crimson AV, Mustang AV, Strong (SnapAV), and Video Mount Products (VMP) - to their closest Expert Mounts equivalent. Search a part number such as Chief CMS0406, Peerless-AV EXT107, or Premier APP-1824 and jump straight to the fixed pipe, telescoping extension, or coupler combination that matches its drop length.
Expert Mounts covers fixed threaded pipes from 2" to 48", telescoping extensions from 8-12" up to 44-72", and couplers, all in 1.5" NPT. Because these are dimensional equivalents rather than identical OEM parts, every row shows a match type - Exact, Closest, More Capable, Combo, or EM Equivalent - and a note explaining exactly how the fit compares. Need a bulk quote or a drop length that is not listed? Ask the AI assistant at the bottom-right of any page or call 1-800-585-8795.
How to Use This Cross-Reference
Every extension column and drop pipe listed here uses the industry-standard 1.5" NPT thread, so the Expert Mounts equivalent threads onto the same ceiling plate, coupler, and mount head as the original part - no adapter required.
- Find your part. Use the brand menu to jump to your manufacturer - Peerless-AV, Crimson AV, Premier Mounts, Chief, Mustang AV, and 13 more - then locate your competitor part number in the left column.
- Read across to the Expert Mounts equivalent. The linked SKU is the 1.5" NPT drop-in or closest-fit build for that drop length.
- Check the match type and note. Each row is flagged with a match type, and the note spells out the exact length or fit difference.
- Order or get help. Click the linked Expert Mounts SKU to view it, or ask the on-site AI assistant (bottom-right) or call 1-800-585-8795 for a fit check or bulk quote.
Match types explained:
- EXACT - the same drop length in a fixed 1.5" NPT pipe.
- EM EQUIVALENT - the Expert Mounts own-brand telescoping column made for that size.
- MORE CAPABLE - covers the full competitor range with extra adjustment.
- CLOSEST - the nearest single part; the note gives the exact difference.
- COMBO - fixed pipes plus a coupler (or a telescoping section) that add up to the target drop, kept under 48" where possible to avoid an oversize shipping surcharge.

Frequently asked questions
How do I find the Expert Mounts equivalent of my extension column part number?
Jump to your brand's section below - 18 brands and 215 part numbers, ordered by catalog size from Peerless-AV down - and locate your competitor part number in the left column. Read across to the linked Expert Mounts equivalent, its match type (Exact, Closest, More Capable, Combo, or EM Equivalent), and a note explaining any length or fit difference. Every listed equivalent uses the same 1.5" NPT thread as the original. If your part is not listed or you need a custom drop length, ask the on-site AI assistant at the bottom-right of any page or call 1-800-585-8795.
Are Expert Mounts extension pipes compatible with Chief, Peerless-AV, Premier, and Crimson ceiling mounts?
Yes. TV and projector ceiling-mount extension columns are built to a shared 1.5" NPT thread standard, so an Expert Mounts fixed pipe, telescoping extension, or coupler threads directly into the same ceiling plate, coupler, and mount head used by Chief, Peerless-AV, Premier Mounts, Crimson AV, Mustang AV, Strong (SnapAV), VMP, and the other brands listed here. That makes it a straightforward replacement for a discontinued or hard-to-source column. These are 1.5" NPT hardware equivalents, not always identical parts, so check the note on each row for any length difference, and confirm your existing hardware is 1.5" NPT before ordering.
What is a 1.5" NPT extension column, and what thread do these use?
A 1.5" NPT extension column is the threaded drop pipe between a ceiling plate and a TV or projector mount. The 1.5" NPT spec (also written 1-1/2" NPT) is the National Pipe Thread trade size on that connection, and it is the standard shared by most AV ceiling mounts, so nearly every part on this page uses it. Expert Mounts offers fixed threaded pipes from 2" to 48", telescoping extensions from 8-12" up to 44-72", and couplers, all in 1.5" NPT.
Are these identical to the original manufacturer parts?
No. They are 1.5" NPT dimensional equivalents, not OEM parts. They match on the thread standard and on drop length, but finish, materials, and construction can differ. The match type and note on each row state exactly how the Expert Mounts option compares - an exact length match, a closer or more capable adjustable range, or a combination of pipes that reaches the same drop.
What is the Expert Mounts equivalent of the Peerless-AV EXT107 extension column?
The Peerless-AV EXT107 is a fixed 7 ft (84") drop. Its Expert Mounts equivalent is a Combo build: two NPT42 fixed 1.5" NPT pipes joined by an 11AC001 coupler for about 84". Building it from two 42" pipes keeps every piece under 48", which avoids the oversize shipping surcharge a single long pipe would add. The linked SKUs are in the Peerless-AV section above.
What is the Expert Mounts equivalent of the Premier Mounts APP-1824?
The Premier Mounts APP-1824 is an 18"-24" adjustable extension column. Its Expert Mounts equivalent is the EXT2036 telescoping extension, which adjusts 20"-36" on a 1.5" NPT thread. It is flagged EM Equivalent because it is our own-brand adjustable counterpart; for a drop between 18" and 20", use a fixed Expert Mounts pipe instead. Full details are in the Premier Mounts section above.
