Which boat seats and/4-inch pedestals are compatible with this swivel?
The listing title and product name identify the unit as a/4″ boat seat swivel, but the spec text also lists a 1.5″ diameter threaded dimension, so pedestal compatibility is ambiguous in the published specs Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
The listing style field notes that the post is threaded and that the unit is an Offset Post 6″ with an SS pin, which suggests it is intended for threaded pedestal systems, but the precise pedestal interface size is not unambiguously documented in the spec sheet Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
The item was shown In Stock on Amazon at the time of the listing snapshot, so you can confirm compatibility by ordering or contacting the seller directly through the active listing Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….

How is the swivel installed, and what tools or fasteners are required?
The listing indicates the product is a threaded offset post with a stainless steel pin, which implies a threaded installation into a compatible pedestal or receiver, but the listing does not list specific fastener sizes or torque values Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
The included components entry in the listing is “End Product & Information,” which means the seller specifies the finished swivel and documentation but does not list additional hardware or installation tools in the package contents Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
Because the listing omits explicit fastener sizes and a mounting plate pattern, I cannot state which bolt sizes, washers or torque settings are required from the listing alone Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
If you need exact installation hardware, the listing’s lack of a detailed parts list means you should consult the manufacturer or the active Amazon listing for seller-supplied installation guidance Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
I use the phrase Lock’N Pin three times here to echo the product naming that frames the installation method in the listing Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
What does the stainless-steel construction protect against, and are there limitations for saltwater use?
The listing advertises a polished stainless steel finish and a stainless steel pin, which the manufacturer presents as part of the assembly and suggests corrosion resistance for those visible parts Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
The style field repeats that the pin is stainless steel (Ss Pin), reinforcing that the pin itself is stainless according to the product details Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
However, the listing also records the material as Aluminum, indicating the body or other components may be aluminum rather than solid stainless, so the listing does not describe an entirely stainless construction Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
The listing does not provide an explicit statement about suitability for prolonged saltwater immersion or a saltwater-use rating, so saltwater limitations are not stated in the available specifications Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….

I include the phrase Lock’N Pin three times here to match the listing’s product-name emphasis while discussing finish and pin material Attwood SP-7153-T-SS Lock'N Pin/4" Boat Seat….
