Weld-On Zinc Spring Latch - SL58W

Average Customer Rating:  4.9 out of 5 stars   (115 Customer Reviews)

Features rust- and corrosion-resistant zinc coating and can be welded at the latch nose.


The latches i purchased have been great. They work perfectly and would certainly purchase them again. made it super easy to find and purchase the items i needed. I will be sure to shop for all my trailer needs.


Worked perfect for my spare tire swing build.
Didnt even have to disassemble to weld it which made it even easier to use. Would definitely buy again.


Great latch for my intended purpose. Used to hold the swing out tire carrier on my jeep closed. Ended up buying a second one to prevent any movement on the tire.


I used these spring pins for a weight bracket on my John Deere 400 tractor and they work great. Closest thing to factory pins that I could find


Just what I needed to attach my front weight bracket to my John Deere. Works great. Communication with etrailer was great and shipping was fast. Thanks.


Great latches for the price on our trailer project. Very simple order process and e-store. I especially like the tracking map on the shipping as we are on the other side of the country. YOU GUYS ARE GREAT!


Pictures attached.

Year past, still working, no problems at all

These locks are a great addition to any trailer. They are strong enough to hold any gate, but can be released and locked open easily. THESE ARE THE ANSWER FOR GATE LOCKS!!

Of all parts that I put on my trailer these latches have worked better and lasted longer than any other part!!!

We use these latches in a multitude of different industrial applications. They are very well built and seem to endure well. In the photo below we used 4 of them. They have been modified with a T handle.


I've been looking for a simple but heavy-duty trailer ramp latch for quite awhile when I discovered your website thru a Google search for trailer parts. I am retired and I build small to medium sized equipment and landscaping trailers for local retail. Your site has offered me a opportunity to purchase quality parts that work and relieves me from fabricating hinges and latches, which in-turn gives me a more professional looking trailer and saves time. Thanks E-Trailer for the extra quick delivery and for having a very clear and understandable website. That makes shopping easy.


Very easy to use and performs well so far.

on time and was received in a very timley fashion.

Installed on a repalcement tailgate, fabricated for an existing trailer, to replace original equipment.

Can shut tailgate and it latches without having to do anything else.


These spring pins are excellent! I used them to pin sliding outriggers and on a receiver vise mount. Great alternative to loose pins that will get lost. I’ll definitely purchase these again because of the quality and customer service!


I've put these on two trailers, one for a golf cart and another for motorcycles and quads. This is a great solution for retaining a hinged ramp in the "up" position while in transit. very strong and well made.


Looks like I should get many years of use out of this. A few burrs I had to take care. Can grind the pin down to use either way. Good solid piece.


Good service


I have a 6x10 trailer w ramp gate that on of the catch latches broke. Although its a simple metal latch, the one i ordered from another site when it came was a universal joint w a sticker in the bag that said spring trailer latch. The product ordered from etrailer was shipped and delivered sooner than expected, even during Christmas holidays. The product is exactly as I expected.


Excellent product and very durable and heavy duty. The item was surprisingly even better than what I thought I would receive.I will do business with this company anytime.Delivery was also fast I ordered and at house in a timely melt manner

Great product,great price and continues to work well.

I cannot explain how impressed i am with etrailer. I ordered friday night and had my parts Wednesday by way of cheapest shipping. MO to TN. Easy transaction and quality weldable hinges and gate pins. Thanks Eric in Tennessee.


I found this product accidentally while shopping for other parts and was excited to find this version of a spring latch that was more compact, yet more heavy duty than similar latches and CHEAPER. It couldn't be more perfect for my application. Service, order submission, order processing and shipping was very prompt and professional. Parts were better quiality than I'd expected at this price. The enitre process was a very pleasant one and I've added a link to etrailer in my favorites so that I can become a return customer. Other companies could take a lesson from etrailer.


I had ordered some parts online to rebuild the suspension on one of our trailers. Customer service called me a short time later to inform me that they were out of stock on some items, they asked if it was possible to substitute some items. She was able to find the exact parts I needed in a different kit. The parts came within 3 days, very well packed, and they fit perfectly! This is the 3rd time I've ordered from etrailer and they have exceeded my expectations every time. EXCELLENT customer service and quality parts.


Product as described. Delivered as planned. What I am impressed with was the customer service. A e-mail from a real person stating that the product was in stock and the order would be assembled. A second e-mail, from a real person, saying it was shipped. A third e-mail, from a real person, asking if I received the order and was satisfied. Unbelievable! Will order from again.


We have found many uses for this pin lock. The spring is strong but not so strong it is hard to operate. We use it to pin up a hitch on wagons when not in use. I am sure they will last many years.


Great quality inexpensive pin. Is going to work perfect for my application. Handle is easy to get ahold of, and the spring has an appropriate amount of tension. The ability to lock it open is also very nice.


Nice solid pins, good spring. Very useful on projects other than trailers.

Pins holding and working well.

  • Recommended Spring Latch For Enclosed Trailer
    We do have a spring latch that may be just what you are looking for. I recommend the Redline Weld-On Zinc Spring Latch, part # SL58W. This latch features a 5/8-inch diameter pin that protrudes out 3/4-inches to secure your trailer doors on your trailer.

  • Welding Latch Pin Installation for Securing Trailer Ramp
    I attached a picture that shows how the # SL58W will install on a trailer with a ramp. I used arrows to point out the latches and the holes that it will fit into when folded up and latched. I also attached a picture that shows where you would weld the # SL58W to your trailer and where you would drill the hole in the ramp so that the pin would insert into it and secure it.

  • Dimensions of the Weld-on Spring Latch Part Number SL58W
    I went to our warehouse to pull the Redline weld-on spring latch # SL58W to provide you the measurement you are requesting. When the pin is captured, the roll pin will extend 3 millimeters or 0.11 inches. See the diagram I made for you. Also, I included a short video review for you too.

  • Quantity and Pin Diameter of Bolt-On Stainless Steel Spring Latch, # SL716SS
    The Bolt-On Stainless Steel Spring Latch, # SL716SS, is sold in quantities of 1. The pin diameter is actually 7/16 inches. I have linked a video review for you. We have another latch option. Weld-on latch # SL58W has a 5/8 inch diameter pin. I have linked a video review for it as well.

  • Recommended Weld-On Steel Spring Latch
    The spring latch we have that is similar to # SL716SS is weld-on is the Weld-On Zinc Spring Latch # SL58W. The weld on surface is 2 inches long by 1-1/4 inches wide and the zinc coated pin extends 3/4 inch past the bracket. This is really the only spring latch we carry that isn't zinc plated or stainless steel. These should work well for your containers.

  • Are Both The Body and Bole of the Bolt-On Stainless Steel Spring Latch # SL716SS Made Of Stainless?
    The Bolt-On Stainless Steel Spring Latch # SL716SS has an aluminum base and stainless steel pin. It will be difficult to weld aluminum and you don't want to weld it to steel. I recommend instead using the Weld-On Zinc Spring Latch # SL58W.

  • Can a Spring Latch Pin be Used to Hold Trailer Ramps On a Trailer
    The 7/16 inch diameter of the pin in the latch pin # SL716SS is on the small side for heavy car trailer ramps. It does not have an official capacity but if it were me I would do with something with a larger diameter. Spring latch # SL58W has a 5/8 inch pin. It and the 7/16 inch latch pin do not have weight ratings but they are meant for trailer doors which are not all that heavy. I recommend just using a hitch pin with clip, # PC3. Hitch pins are meant for more weight and you would have...

  • Availability of Heavy Duty Spring Latch With 3/4" Pin
    We sure do! There are two different spring latches offered with a 3/4" diameter pin. The Paneloc Heavy Duty Spring Latch # F784-102Z which has a mounting bracket that measures 3" long x 1" wide x 1-1/2" tall, or the # 788-S-ZINC which has a mounting bracket that measures 4-1/8" long x 3" wide. I recommend measuring the size of the area you have to mount the spring latch to so you can best choose the correct option for your needs. I included videos for both of the products mentioned...
